Gibson Serial Number Lookup: Free Decoder Tool + Complete Dating Guide

Where To Locate Your Gibson Guitar’s Serial Number

On the Interior Label

Found on acoustic and hollow-body electrics. Look through the soundhole or f-holes for a paper label, white oval on early models, orange oval from 1947 onward. The serial number is handwritten or stamped directly on this label.

Acoustics & Hollow Bodies

Back of the Headstock

On solid body and semi-hollow electrics, the number is ink-stamped, silkscreened, or die-stamped into the wood depending on the era. Post-1970 models also have a “MADE IN USA” stamp directly below the serial number.

What About Factory Order Numbers (FONs)?

Nearly all vintage Gibson acoustics and hollow-bodies also have a Factory Order Number, a separate number ink-stamped directly onto the bare wood inside the body, not on a label. FONs were used from 1902 to 1961 and are often more reliable for dating than the serial number alone. Look for a stamped or handwritten number on the interior wood when you peek through the soundhole. Use the decoder tool above to decode both serial numbers and FONs.

Gibson Factory Order Numbers (FON): The Complete Dating Guide (1902 to 1945)

Before Gibson developed a formal serial number system, every instrument that left the Kalamazoo factory was assigned a Factory Order Number, a production batch code stamped or written in ink directly onto the bare wood inside the body. On most pre-war Gibson acoustics, the FON is the primary dating method. No other single clue is more reliable. Understanding how to read a Gibson FON can mean the difference between correctly identifying a rare 1930s archtop and misattributing it by a decade. If you’re trying to determine how the year of manufacture affects your Gibson’s value, the FON is where that research begins.

Where to Find a Gibson Factory Order Number

FONs are typically found on the interior back or side bracing, stamped or written in pencil or ink. On archtops, look through the f-holes with a flashlight. On flat-tops like the J-45, J-50, and SJ or the early LG series, peer through the soundhole and look toward the back bracing. The number may appear faint or partially worn. This is entirely normal on genuine pre-war instruments and is itself a sign of authenticity rather than a red flag.

How to Read Gibson FONs Across Every Production Era

Gibson’s Factory Order Number system went through several distinct phases between 1902 and 1945. From 1902 through 1916, a simple sequential system ran from 1 to 3,650, with no letters or prefixes. Numbers then jumped to the 11,000 to 12,000 range from 1917 through 1923, briefly used an optional “A” suffix in 1924 and 1925, then dropped back down to the 8,000 to 9,999 range from 1925 through 1931. The early 1930s saw another reset, with numbers starting again from 1 through 1934. The system became much more reliable in 1935 when Gibson introduced alphabetical suffixes, a letter at the end of the batch number indicating the production year, running from A in 1935 through H in 1942. From 1940 through 1945, numbers ran from 1 to 7,900 and letters may or may not be present. Because many of these number ranges were reused across different decades, the FON alone is rarely definitive. Always examine the physical features of the instrument alongside the FON itself.

Gibson FON Dating: The Banner Era & Post-War Recovery (1942 to 1951)

The years surrounding World War II represent the most inconsistent period in Gibson’s entire serialization history. Production was dramatically reduced, quality control on record-keeping suffered, and many instruments left the Kalamazoo factory with incomplete or missing FONs entirely. Despite this, guitars from the Banner era (1942-1945) and the immediate post-war recovery (1945-1951) are among the most sought-after vintage instruments ever made. A confirmed date from this window, when combined with the right physical features (banner-on-headstock placement, bracing pattern, tuner type, and logo style), can meaningfully change what your guitar is worth.

How to Identify a Banner Era Gibson (1942 to 1945)

The most reliable identifier of a wartime Gibson is the “Banner” headstock logo, a small pennant reading “Only a Gibson is Good Enough” that appeared on instruments made from 1942 through 1945. If your guitar has this banner, it was almost certainly made during the war years regardless of what the FON says. Banner-era instruments are also identifiable by their use of alternative tonewoods, simplified binding, and in some cases non-adjustable truss rods as materials became scarce. These wartime compromises produced some of the most tonally remarkable acoustics Gibson ever made. They tend to be lightly built and unusually resonant for their size, and most are now hard to find in clean original condition.

The Banner logo is the single most reliable identifier of a wartime Gibson. If your guitar has this, it was almost certainly made between 1942 and 1945.

Post-War Gibson FONs (1945 to 1951)

As Gibson ramped production back up after the war, FON record-keeping gradually stabilized, but the 1945-1951 window remains unreliable by Gibson’s own standards. The ranges below show the best available data for instruments from this period. For guitars from 1945 through 1947 in particular, FONs are not considered reliable, and dating by physical features is the better approach. Gibson also expanded its electric guitar line during this era, introducing the ES-350, ES-300, and ES-175.

Gibson FON Dating: The Standardized Alphabetical Prefix Era (1952 to 1961)

After years of inconsistent record-keeping, Gibson introduced its most reliable pre-modern FON system in 1952, an alphabetical prefix at the beginning of the Factory Order Number indicating the production year. Unlike the suffix system of the 1930s where letters appeared at the end of the number, these prefix letters appear at the very start and are well-documented and consistent across the entire decade. Find the letter at the beginning of your FON and match it to the chart below to identify your guitar’s production year.

This era also covers what many consider the greatest decade in Gibson’s entire history, encompassing the original Les Paul Goldtops and Standards, the birth of the ES-335, ES-345, and ES-355, the introduction of the PAF humbucker, and the peak of Kalamazoo craftsmanship. Year-of-manufacture has a dramatic effect on value during this era, and the difference between a 1958 and a 1959 example can be substantial.

Decoding Gibson Serial Numbers: The White Label Era (1902 to 1947)

Gibson’s earliest serial numbers were handwritten or stamped on a white oval paper label inside the body of the instrument, visible through the soundhole on flat-tops or through the f-holes on archtops. These labels predate the orange oval that came later and are found on some of the rarest instruments Gibson ever produced. The serial numbers from this period ran sequentially from 1 through 99,999 and are generally reliable for dating when cross-referenced with physical features.

An authentication note: genuine white label instruments from this era will show their age. The ink or pencil used for handwritten numbers will have faded or browned naturally over a century. If you encounter a white label with crisp, clean ballpoint pen writing or modern-looking ink, treat it as a red flag for a counterfeit or a replaced label.

Gibson White Oval Label: 1902 to 1947

The white oval label is Gibson’s earliest serialization method, found inside acoustic and archtop instruments from 1902 through 1947. Genuine examples will show natural aging: browning of the paper, faded or oxidized ink, and handwriting consistent with fountain pen or early stamping. A label that looks too clean or uses modern ballpoint pen ink is a red flag for a counterfeit or replaced label.

Gibson A-Prefix Serial Numbers (1947 to 1961)

The A-prefix serial number system is one of the most reliable dating tools Gibson used during the postwar era. If your Gibson has a serial number beginning with the letter A followed by a four- or five-digit number, this chart will give you the year. These numbers were used across multiple label types, so don’t be thrown off if your label isn’t orange. A-prefix serials appear on white labels, orange labels, and VERY occasionally on instruments with no label at all where the number was stamped directly onto the back of the headstock. The system ran from A 100 in 1947 through approximately A 34,645 by the end of 1960, at which point Gibson’s serialization began to break down into the chaotic reused number system covered in the next section. Always cross-reference your A-prefix number against physical features for a confirmed date. A one-year margin of error is not uncommon.

Gibson A-Prefix Serial Number: Orange Label Example

This orange oval label shows a typical A-prefix serial number from the postwar era. Note that A-prefix numbers also appear on white labels and headstock stamps. The prefix letter is what matters for dating, not the label color.

Gibson Ink Stamp Serial Numbers: Solid Body Electrics (1952 to 1960)

While Gibson was using the A-prefix label system on its hollow and semi-hollow instruments throughout the 1950s, solid-body electric guitars received their serial numbers differently. The number was stamped directly onto the back of the headstock finish in ink, with no interior label at all. This system was used on the Les Paul Goldtop, Les Paul Custom, Les Paul Special, Les Paul Junior, and their successors from 1952 through approximately 1960.

The ink stamp system is straightforward once you know the rule: the first digit of the serial number is the last digit of the production year. Everything after it is a sequential production number. A serial beginning with 7 was made in 1957; a serial beginning with 9 was made in 1959. The graphic below makes this immediately clear, and the year key shows you exactly what was happening at the Kalamazoo factory in each year of the system’s run.

1955 Gibson Les Paul Custom: Ink Stamp Serial Number

On solid-body electric guitars, Gibson stamped the serial number directly onto the back of the headstock finish rather than using an interior label. This 1955 Les Paul Custom shows a typical example: a five-digit number with no prefix, ink stamped onto the finished headstock.

Gibson Serial Numbers 1961 to 1970: The Reused Number Era

If you have a Gibson from the 1960s and your serial number appears to match multiple years, you’re not doing anything wrong. Gibson’s serialization during this period is genuinely one of the most chaotic in the history of American instrument manufacturing. Beginning in 1961, Gibson exhausted their existing number sequences and began reusing old ranges rather than introducing a new system. The result is that tens of thousands of serial numbers from this era were stamped onto instruments in two, three, or even four different years, making the serial number alone nearly useless as a dating tool without physical corroboration.

This affects some of the most collectible instruments ever made: 1960s SGs, ES-335s, ES-175s, Firebirds, and Flying Vs all fall within this window. The chart below maps every known range to its possible production years. Where a number could belong to multiple years, all possibilities are listed. To narrow it down, you’ll need to examine the potentiometer date codes, the pickup type, the tuner style, the headstock profile, and the presence or absence of a volute. For a 1960s Gibson, physical feature dating is the only reliable way to confirm a date.

The Norlin Era: 1969 to 1984

In 1969, Gibson’s parent company Chicago Musical Instruments was acquired by ECL, a South American brewing and industrial conglomerate that collectors and historians refer to collectively as Norlin, the name the combined entity eventually adopted. The Norlin period runs from 1969 through 1984, when the company was sold to a group of investors including Henry Juszkiewicz, who returned Gibson to American private ownership. The Norlin era has a complicated reputation. On one hand, it produced genuinely playable and sonically capable instruments that are some of the best value in the vintage market today, precisely because of their stigma. On the other hand, the period is defined by a series of cost-cutting and quality-control decisions that moved Gibson away from the construction methods and materials that defined the golden-era instruments of the 1950s and early 1960s. The changes most associated with Norlin include three-piece laminated necks, thicker finishes, the volute, the Nashville bridge, and inconsistent quality control on the production floor. Understanding where the Norlin era begins and ends is essential context for everything in the serial number and physical feature dating sections of this guide. A guitar that dates to 1968 and one that dates to 1970 can be very different instruments despite being built just two years apart, and the Norlin transition is the reason why.

Phase 1: Six-Digit System (1970 to 1975)

Following the acquisition of Gibson by Norlin Musical Instruments in 1969, the chaotic reused number system of the 1960s was finally retired. From 1970 onward, Gibson used a straightforward six-digit sequential serial number stamped on the back of the headstock. From this point every Gibson also received a “Made in USA” stamp directly below the serial number as required by US customs regulations. If you’re trying to date a 1970s Gibson guitar and your instrument has a six-digit number with a “Made in USA” stamp, it was almost certainly made between 1970 and 1975. The volute (a small thickened ridge at the rear of the headstock) also appears on most models from this period and is one of the quickest physical identifiers of an early Norlin-era instrument.

Gibson “Made in USA” Headstock Stamp: From 1970 Onward

Every Gibson built from 1970 onward carries this stamp below the serial number. Its presence immediately confirms a post-1969 production date, and its absence on an instrument claiming to be from the 1970s is a red flag worth investigating carefully.

Phase 2: Decal Prefix System (1975 to 1977)

From 1975 through 1977, Gibson introduced a brief but distinct transitional system: an eight-digit serial number applied as a gold decal on the back of the headstock rather than a deep ink stamp. The first two digits of this number indicate the production year, making these instruments relatively straightforward to date once you know the system. If your Gibson has a serial number that looks like a gold transfer sitting under the finish rather than stamped into the wood, you almost certainly have one of these transitional instruments. The decals are sometimes prone to wear or partial peeling after decades of use, so don’t be alarmed if yours shows signs of age. Three prefix codes were used across this short window: 99 for 1975, 00 for 1976, and 06 for 1977.

1975 Gibson Les Paul Custom: Waterslide Decal Serial Number

This photo shows the gold waterslide decal serial number on the back of the headstock, the format used from 1975 through 1977. Notice how the number sits on top of the finish rather than being stamped into it. After decades of play wear, these decals can show signs of lifting or fading at the edges, which is completely normal and expected on a genuine instrument from this period.

Gibson Serial Numbers 1977 to Present: The Modern Eight & Nine-Digit System

In 1977, Gibson introduced the eight-digit serial number system that, with minor variations, remains in use on every Gibson built today. Whether you’re trying to date a 1980s Les Paul Standard, a 1990s SG, or a guitar that came out of the Nashville factory last year, this is the system that applies. It’s one of the most logical serialization formats Gibson ever used, and once you understand the structure, it takes about ten seconds to date any modern Gibson accurately.

The key is knowing that the first and fifth digits together give you the last two digits of the production year, and the second, third, and fourth digits tell you the day of the year the guitar was stamped. The remaining three or four digits are a sequential production number indicating how many instruments were completed that day, which is why some Gibson serial numbers are eight digits and others are nine.

How to Date a Les Paul Classic With an Ink Stamp Serial Number

For much of its production, the Les Paul Classic used a unique ink-stamped serial number system that runs from 1989 through 2014 and differs from both the vintage 1950s ink-stamp system and the modern eight-digit Gibson serial format. On examples made between 1989 and 1999, the first digit is the last digit of the production year, followed by a space, and then three or four digits indicating the guitar’s place in production for that year, giving you either a four- or five-digit total. The earliest examples from 1989 carry only four digits total. From 2000 through 2014, the format changed to six digits with no space. The first two digits are the last two digits of the production year, followed by four production rank digits. A serial reading 071234, for example, was made in 2007 and was the 1,234th instrument completed that year. No “Made in USA” stamp appears below the serial on the standard Classic, which kept this ink-stamp format all the way through 2014. The often-repeated claim that Gibson switched the Classic to the modern stamped serial in 2007 is a misunderstanding: that change applied only to a handful of 2007 Classic offshoot models built on the standard Gibson USA line, not to the core Classic (see below).

Gibson Les Paul Classic: Ink Stamp Serial Number

The Les Paul Classic uses an ink-stamped serial number on the back of the headstock that can easily be mistaken for a vintage 1950s stamp at first glance, but look closely and the font is different. Gibson used several different fonts on the Classic over its production run, but none of them match the authentic vintage ink-stamp font used on original 1950s solid-body instruments. No “Made in USA” stamp appears below the serial on most examples, which is itself a dating clue.

The 2007 “Offshoot” Explosion

There’s one exception to all of this, and it only shows up in 2007. That year Gibson put out a few new spins on the Classic as regular catalog models, plus several runs in its “Guitar of the Week” series. These guitars went down the normal Gibson USA line instead of being handled like historic reissues, so they got the regular modern 9-digit impressed serial (the first and fifth digits give you 2007) and a “MADE IN USA” stamp instead of the Classic’s usual ink stamp. That’s the only time you’ll see a Les Paul Classic with that format, and even then it’s only on a few specific models.

So if you come across a 2007 Classic with a stamped 9-digit number, don’t assume it’s a refinish or a parts guitar. Check the specs first. It’s almost certainly one of these three:

The core model stayed true. Every other standard-production Les Paul Classic, before and after 2007, kept the ink-stamped serial with no “Made in USA” stamp, right up to the end of the run in 2014. If your Classic has the plain ink stamp and no “Made in USA” mark, just date it with the ink-stamp formats above. The 2007 stamped exception doesn’t apply to it.

Gibson Custom Shop & Historic Reissue Serial Numbers

Gibson Custom Shop and Historic Reissue instruments use entirely different serialization formats from standard Gibson USA production, and to make things more complicated, different Custom Shop models use different formats from each other. A Gibson R9 Les Paul reissue is serialized differently from an SG reissue, which is serialized differently from a Custom Shop ES-335, which uses yet another format from a carved-top archtop. If your Gibson has a Custom Shop serial number that doesn’t match anything in the standard modern decoder, this section is where you need to be.

Modern Custom Shop Models: The CS Prefix

Standard modern Gibson Custom Shop instruments (meaning Custom Shop builds that aren’t Historic Reissues of a specific vintage year) carry a CS prefix ink-stamped on the back of the headstock. The CS prefix immediately identifies the instrument as Custom Shop production. The digit immediately following CS is the last digit of the production year, and the remaining three or four digits are the guitar’s sequential rank in that year’s Custom Shop production. A serial reading CS91234 was built in 1999 and was the 1,234th Custom Shop instrument completed that year.

Gibson Custom Shop: CS Prefix Ink Stamp Serial Number

Modern Gibson Custom Shop instruments carry a “CS” prefix ink-stamped on the back of the headstock, immediately identifying them as Custom Shop production. The digits following CS tell you the production year and the guitar’s place in that year’s build sequence.

Historic Reissue Les Paul Models: Ink Stamp Format

Gibson’s Historic Reissue Les Paul guitars, the R4, R7, R8, R9, R0 and related models, use an ink-stamped serial number on the back of the headstock where the first digit indicates the vintage year being reissued, not the year the guitar was made. A serial beginning with 9 is a 1959 reissue. A serial beginning with 8 is a 1958 reissue. The second digit is the last digit of the actual production year, and the remaining three or four digits are the production rank. So a serial reading 991234 is a 1959 Les Paul reissue, built in 1999, and was the 1,234th Historic Reissue completed that year.

Gibson R9 Historic Reissue: Ink Stamp Serial Number

Les Paul Historic Reissues carry an ink-stamped serial number where the first digit is the model year being reissued, not the production year. A “9” prefix means it’s a 1959 reissue, an “8” means a 1958 reissue, and so on. The second digit is the last digit of the actual year the guitar was made, followed by the production rank.

Historic Reissue SG & Other Models: Impressed Serial Numbers

SG Historic Reissues, Firebird reissues, Flying V reissues, and several other Custom Shop models use an impressed serial number, physically pressed into the wood of the headstock rather than ink-stamped. The format reverses the Les Paul reissue logic: the first digit is the last digit of the actual production year, the middle digits are the production rank, and the final digit is a model year code identifying which vintage year is being reissued. A 1 at the end means a 1961 SG Standard reissue, a 3 means a 1963 SG Custom, Special, or Junior, and so on. The model code table below covers every reissue code used in this format.

Gibson SG Reissue: Impressed Serial Number

SG reissues and several other Custom Shop models use an impressed serial number physically pressed into the wood of the headstock rather than ink-stamped. The format reverses the Les Paul reissue logic: the production year digit comes first, followed by the production rank, with the model year code at the end.

ES Reissues & Carved-Top Custom Shop Models

Gibson’s Custom Shop ES reissues and carved-top archtops use yet another format. The 1958 ES-335 reissue and 1959 ES model reissues carry their serial number on a label inside the f-hole with no headstock stamp. The label uses an A-prefix format where the digit following A indicates the model year being reissued. The 1961 and 1964 ES reissues carry both an impressed headstock stamp and a matching f-hole label stamp. Carved-top Custom Shop models such as the L-5 CES and Super 400 use the same split-year format as standard modern Gibsons (first and fifth digits give the production year, digits two through four give the day of the year), with the first digit reading 2 on all instruments made from 2000 onward.

Dating Your Gibson By Physical Features: Beyond the Serial Number

A serial number is your starting point, not your finish line. On vintage Gibsons from the 1960s, it may be nearly useless on its own, and even on instruments from other eras a serial number can be duplicated, replaced, or simply inconclusive. The physical features of the instrument (headstock logo, tuners, knobs, pickups, hardware, neck construction) tell a story that can’t be faked as easily and can date a Gibson with far greater precision than the serial number alone. Every section below covers a specific feature, what it looked like in each era, and exactly what to look for when you’re trying to pin down a production year. Used together, these features form a complete picture that experienced dealers, auction houses, and insurance appraisers rely on when a serial number isn’t enough.

Gibson Headstock Logo Evolution: A Complete Dating Guide

The Gibson headstock logo changed more times than most collectors realize, and each change was distinct enough to serve as a reliable dating tool in its own right. From the thin calligraphic ‘The Gibson’ script of 1908 through the wartime banner era, the postwar block logo transformations, and the Norlin silkscreen years, the logo on the front of the headstock can narrow a production date down to a window of just a few years without ever looking at the serial number. The timeline below covers every major logo variation in Gibson’s history: what it looked like, what years it was used, what makes each version distinctive, and what to watch for when authenticating a vintage instrument.

Gibson Knob Styles By Year: A Visual Dating Guide

The control knobs on a Gibson electric guitar changed five distinct times between 1935 and 1975, and each style was used exclusively enough that the knob type alone can confirm or contradict a claimed production date. Bakelite knobs point to pre-1946 production. Gold speed knobs with no numbers indicate the earliest postwar instruments from 1946 onward. Bonnet knobs in black or gold place an instrument firmly in the 1955-1960 golden era, and their presence on a Les Paul is one of the strongest visual indicators of a genuine late-1950s instrument. Top hat reflector knobs with their distinctive metallic insert are exclusive to 1960-1967, covering the SG transition years and the Firebird era. Witch hat knobs with gold or silver tops indicate 1967-1975 production. After 1975, Gibson’s knob usage became inconsistent across models, and knob style can no longer be relied upon as a dating tool. For anything built before that cutoff, the knob is one of the first things an experienced dealer looks at.

Bakelite Knob: 1935 to 1946

Bakelite Knobs: 1935 to 1946

Gibson’s earliest electric instruments used knobs made from Bakelite, one of the first synthetic plastics, widely used in consumer electronics and instrument manufacturing through the 1930s and into the 1940s. Bakelite knobs have a distinctive appearance and feel that differs from later plastics: they tend to have a slightly waxy surface, a heavier feel than modern knobs, and often show a characteristic aging pattern where the material develops a brownish or amber cast over time even if originally black. Bakelite knobs on a vintage Gibson are a strong indicator of pre-1946 production on electric models.

Dating Indicator1935-1946 OnlyEarly Synthetic PlasticBrownish/Amber Aging

Bakelite can be identified with a simple hot needle test. A heated needle will produce a distinctive phenol smell when touched briefly to Bakelite. The material also tends to feel heavier and denser than later thermoplastics.

Speed Knob: 1946 to 1955

Speed Knobs: 1946 to 1955

After the war, Gibson transitioned to a new knob style that collectors refer to as “speed knobs,” a low-profile, slightly domed design with a flat top. These first appeared on postwar Gibson electrics beginning around 1946 and remained the standard through 1955. The earliest postwar speed knobs have smooth tops with no numbers, a detail that can help narrow down production to the first few years of this era. By the early 1950s, numbers 1 through 10 began appearing on the knob surface. The Les Paul Custom, introduced in 1954, used black speed knobs throughout its run in this era, while the standard Les Paul Goldtop and most other models used gold versions.

Dating Indicator1946-1955Early Examples UnnumberedLater Examples Numbered 1-10LP Custom: Black

If a 1946-1955 era Gibson has speed knobs with no numbers at all, this points to earlier production within the window. Numbered speed knobs came in progressively as the early 1950s progressed.

Bonnet Knob: 1955 to 1960

Bonnet Knobs: 1955 to 1960

In 1955, Gibson introduced what collectors call the “bonnet knob,” a distinctive dome-shaped design that sits higher than the speed knob and has a rounded, bonnet-like profile. These are among the most visually recognizable knobs in all of vintage guitar collecting and are closely associated with the golden era Les Paul Standards, including the Sunburst models from 1958 to 1960. Bonnet knobs came in both black and gold versions. The transition away from bonnet knobs happened partway through 1960 when Gibson began switching to the top hat style, meaning some 1960 instruments will have bonnet knobs and others will have top hats depending on exactly when in the year they were built.

Golden Era Indicator1955-1960Black and Gold VersionsDome/Bonnet ProfileTransitional in 1960

A 1960 Les Paul Standard with bonnet knobs was built earlier in that production year than one with top hat knobs. Since 1960 Sunbursts are among the most valuable guitars ever made, the knob style is one of several details used to narrow down production within that single calendar year.

Top Hat / Reflector Knob: 1960 to 1967

Top Hat / Reflector Knobs: 1960 to 1967

From 1960 through 1967, Gibson used what collectors call “top hat” or “reflector” knobs, a taller design with a wider, flat brim and a metallic reflector insert on the top. These are the knobs associated with the earliest SG models, the late-transitional ES-335 production, and the Firebird series. Both black and gold versions were produced. The reflector insert (a small circular metallic disc set into the top of the knob) gives these knobs their alternative “reflector knob” name and is the single most identifiable visual feature.

Dating Indicator1960-1967Black and Gold VersionsMetallic Reflector InsertSG / ES / Firebird Era

The reflector insert is the key identifier. No other Gibson knob era uses this detail. If the reflector is present, the instrument dates to 1960-1967 or has had knobs sourced from that period.

Witch Hat Knob: 1967 to 1975

Witch Hat Knobs: 1967 to 1975

From 1967 through approximately 1975, Gibson used the style collectors call “witch hat” knobs, named for their tall, tapered profile that comes to a rounded point at the top, resembling a witch’s hat in silhouette. These appeared across the full range of Gibson electric models during the late 1960s and into the early Norlin era. Witch hat knobs can have either a gold or silver-colored top cap, and this detail can sometimes help narrow production within the era.

Dating Indicator1967-1975Gold or Silver Top CapTall Tapered ProfileLate 60s / Early Norlin

Gold-top witch hats tend to appear on earlier examples in this window and on higher-spec models. Silver tops are more common from the early 1970s onward. Used alongside the serial number and other features, the cap color can help narrow a date within the 1967-1975 range.

Not a Dating Tool

1975 to Present: Post-1975, Not Reliable for Dating

After 1975, Gibson began mixing knob styles inconsistently across its model range, and knob type alone cannot be used to date a post-1975 instrument. Speed knobs returned on many models, but different styles appeared simultaneously on different models within the same year and were sometimes swapped between production runs without announcement. Replacement knobs are also extremely common on instruments of this era. For post-1975 Gibsons, the serial number and the physical feature dating guides for neck construction, hardware, and logo are far more reliable than the knob style.

Gibson Tuner Identification: Dating Your Gibson By Its Tuning Machines

The tuning machines on a vintage Gibson are one of the most precise and underutilized dating tools available, precise enough that the difference between a single line and a double line of text stamped on a tuner cover can confirm whether an instrument was built before or after 1964. Gibson used Kluson tuners as standard equipment on its electric models from the early 1950s through the early 1970s, and Kluson changed their cover stamping twice during that window, giving collectors a reliable three-stage timeline within the broader Kluson era. The transition from “Kluson Deluxe” to “Gibson Deluxe” stamping around 1969 adds a fourth marker. Combined with the button style (single-ring before 1960, double-ring from 1960 onward), the tuners alone can narrow a production date to a window of just a few years on most golden-era instruments. This guide covers individual tuners only. Strip tuners used on certain Gibson models are not included here.

Nickel & Chrome Kluson Tuners: Individual Style

No-Line Kluson, 1952 to 1956

Kluson Deluxe: No Line, 1952 to 1956

The earliest individual Kluson tuners used on Gibson solid-body electrics had a plain tulip-shaped plastic button and a smooth metal cover with no text stamped on it. Collectors refer to these as “no-line” Klusons. These appear on the earliest Les Paul Goldtops, the original Les Paul Custom, and other Gibson electrics from the first years of solid-body production through approximately 1956. The absence of any stamping on the tuner cover is the single identifying feature of this variant.

Dating Indicator1952-1956No Text on CoverTulip Button

No stamping on the metal cover is the key. If there is any text at all on the tuner cover, it is not a no-line Kluson. These are among the most reproduced vintage tuners, so examine the metal quality and aging carefully on any instrument where originality matters.

Single-Line Kluson, 1956 to 1964

Kluson Deluxe: Single Line, 1956 to 1964

Around 1956 Kluson began stamping a single line of text (“KLUSON DELUXE”) on the metal tuner cover. This single-line variant is the tuner associated with the most desirable Gibsons ever made: the 1956-1960 Les Paul Standards including the Sunburst models, the original ES-335 from 1958, the ES-345, the ES-355, and the majority of golden-era production across all models. The single line of text runs along the center of the cover plate.

Golden Era Indicator1956-1964One Line of Text on CoverTulip ButtonLes Paul / ES Golden Era

Count the lines of text on the cover. One line = 1956-1964. Two lines = 1964-1969. This is one of the fastest and most reliable ways to distinguish a pre-1964 Gibson from a post-1964 one when the serial number is ambiguous.

Double-Line Kluson, 1964 to 1969

Kluson Deluxe: Double Line, 1964 to 1969

Around 1964 Kluson added a second line of text to the tuner cover, creating the “double-line” variant that remained standard on Gibson electrics through approximately 1969. The double-line Kluson appears on mid-to-late 1960s SGs, ES models, and the transitional instruments of the Norlin era boundary. The two lines of stamped text on the cover plate are immediately visible and distinguish this variant from the single-line version at a glance.

Dating Indicator1964-1969Two Lines of Text on CoverMid-Late 60s SG / ES

A Gibson with double-line Klusons and a serial number in the ambiguous mid-1960s reused range can be more confidently placed after 1964. The double-line Kluson did not exist before that year.

Gibson Deluxe Kluson, 1969 to 1974

Gibson Deluxe: Kluson-Made, Gibson Branded, 1969 to 1974

Around 1969 Gibson began having Kluson manufacture tuners stamped with “GIBSON DELUXE” on the cover rather than “KLUSON DELUXE.” The mechanism and construction are essentially the same as the double-line Klusons that preceded them, but the branding change is an important and precise dating marker. Gibson Deluxe stamped tuners appear on instruments from the early Norlin transition period through approximately 1974.

Dating Indicator1969-1974Stamped “Gibson Deluxe”Early Norlin Era

Read the text on the cover plate carefully. “Kluson Deluxe” = pre-1969. “Gibson Deluxe” = 1969-1974. This single detail can immediately resolve ambiguity on late-1960s instruments with inconclusive serial numbers.

Gold Tuners: High-End & Archtop Models

Kluson Waffle-Back, Gold

Kluson Waffle-Back Tuners: Gold, 1950s & 1968 to 1974

Gold Kluson waffle-back tuners (named for the distinctive grid-textured pattern on the back plate of each tuner) appeared on high-end Gibson electrics in the 1950s, most notably on the ES-5 Switchmaster and the early Les Paul Custom. By the late 1950s, most high-end Gibson models transitioned to gold Grover tuners. However, waffle-back Klusons saw a notable resurgence from approximately 1968 through 1974, appearing again on the Les Paul Custom and SG Custom during the early Norlin period.

Gold Hardware1950s High-End Models1968-1974 ResurgenceLP Custom / SG CustomGrid-Textured Back Plate

Waffle-back Klusons on a Les Paul Custom or SG Custom narrow the window to two distinct eras: early 1950s or 1968-1974. Cross-reference with the logo, neck construction, and serial number to determine which era applies.

Kluson Sealfast, Gold Archtop Tuners

Kluson Sealfast Tuners: Gold, High-End Archtops

The Kluson Sealfast is a premium enclosed-gear tuner used primarily on Gibson’s high-end archtop models: the L-5 CES, the Super 400 CES, and other top-of-the-line instruments. The Sealfast design fully encloses the gear mechanism, providing better protection from dust and debris than open-back tuners, and the gold plating is consistent with the premium specification of the instruments they were fitted to.

Gold Grover Rotomatics, From 1958

Gold Grover Rotomatic Tuners: 1958 Onward

From around 1958, Gibson began fitting gold Grover Rotomatic tuners on its higher-end electric models as an upgrade over the gold Kluson waffle-back. The Grover Rotomatic is an enclosed, self-lubricating tuner with a distinctive round housing and a higher gear ratio than the Kluson, making it more stable and precise for the era. Gold Grovers became the standard premium tuner on models like the ES-355, the top-spec ES-345, and certain high-end versions of other models.

Gold HardwareHigh-End Spec IndicatorFrom 1958ES-355 / High-End ModelsEnclosed Rotomatic Housing

Gold Grovers on a 1958-1964 Gibson are a sign of top-specification original hardware. If a claimed ES-355 or similar high-end model has Klusons instead of Grovers, the tuners may have been replaced.

Gibson Pot Codes: How to Date a Gibson Using Potentiometer Date Codes

Potentiometer date codes (pot codes) are the single most reliable dating tool available on vintage Gibsons from the 1960s, and they are essential reading on any instrument where the serial number is ambiguous or inconclusive. Every potentiometer used in a Gibson guitar carries a stamped code on its casing that identifies the manufacturer and the exact week and year the component was made. On Gibson instruments specifically, the pots are mounted in a way that frequently puts the stamped side of the casing facing inward, meaning the code may be invisible without partially removing the potentiometer from the cavity. Desoldering and removing pots is not recommended for anyone without soldering experience. The most common manufacturer code you’ll encounter on a Gibson is 137, used by Chicago Telephone Supply (CTS). The remaining digits tell you the year and the week of manufacture, and when all the pots in an instrument agree on the same date, that’s as close to a definitive production window as vintage guitar dating gets.

1958 Gibson Les Paul Special, Potentiometer

The date code on a vintage Gibson pot is stamped on the side or back of the casing. On Gibsons specifically, the pots are mounted in the cavity in a way that makes the code difficult to see without removing the control plate or pickguard. Solder residue often needs to be cleaned away first. The code itself is small but worth the effort to find.

The Gibson Volute: A One-Second Dating Check on Norlin Era Instruments

The volute is one of the fastest and most unambiguous dating indicators on any vintage Gibson electric. It requires no tools, no disassembly, and no specialist knowledge to identify. Turn the guitar over and look at the back of the neck where it meets the headstock. If a raised ridge of wood is present at that junction, the instrument was built between 1969 and 1981. If the transition is smooth, the instrument either predates 1969 or postdates 1981. Gibson introduced the volute as a structural reinforcement against headstock breaks, and it appeared across the entire electric model range from its introduction through to its discontinuation in the early 1980s. It started as a subtle, almost imperceptible bump in 1969 and grew larger through the early to mid-1970s, reaching its most pronounced size during the mid-Norlin period.

The volute did not appear fully formed in 1969. It started as a relatively subtle bump and grew larger through the early to mid-1970s, reaching its most pronounced size by the mid-to-late Norlin period. To the trained eye, the size of the volute itself is an additional dating indicator within the 1969-1981 window. A small, barely-there volute points to the earliest years of this era, while a large, aggressive volute is characteristic of mid-1970s production.

Gibson Neck Construction: One-Piece Mahogany, Three-Piece Mahogany, and Three-Piece Maple

The construction of the neck is one of the most telling physical indicators of where a Gibson falls in its production history. From the very beginning of Gibson’s electric guitar production through approximately 1969, every Gibson electric neck was carved from a single uninterrupted piece of mahogany. Around 1969, as Norlin assumed ownership, Gibson began transitioning to a three-piece laminated mahogany construction. By approximately 1975, the material changed again, this time to three-piece maple, which produces a noticeably brighter and harder tonal character. Neither transition happened overnight, so neck construction is most useful as a confirming detail rather than a standalone dating tool.

One-Piece Mahogany, Pre-1969

One-Piece Mahogany Neck: Through 1969 (preferred)

From Gibson’s earliest electric models through approximately 1969, every Gibson electric neck was carved from a single piece of mahogany: no glue joints, no laminations, no center strips. The one-piece mahogany neck is the construction method associated with every golden-era Gibson ever made. Among collectors and players, it is strongly preferred, both for tonal reasons and for its association with the most desirable instruments Gibson ever produced. Identifying it is straightforward: look at the back of the neck in a raking light. There will be no visible seam, center strip, or glue line.

Most DesirableThrough 1969No Seams or Glue LinesAll Pre-Norlin ModelsWarm Resonant Tone

A one-piece mahogany neck places a Gibson solidly in the pre-1969 golden era construction window. Combined with the absence of a volute, it is a strong positive indicator of correct-era construction.

Three-Piece Mahogany, 1969 to 1975

Three-Piece Mahogany Neck: 1969 to 1975

Around 1969, as Gibson transitioned into the Norlin ownership period, the factory began moving away from one-piece mahogany necks toward a three-piece laminated construction, built from two outer sections of mahogany with a center strip glued between them. The transition was not immediate or uniform; some 1969-1972 instruments still have one-piece necks. Three-piece mahogany necks are identifiable by the two thin glue lines running the length of the back of the neck, one on each side of a center strip.

Dating Indicator1969-1975Two Visible Glue LinesCenter Strip ConstructionEarly Norlin Era

Look for two thin parallel seams running the length of the back of the neck in a raking light. One seam on each side of a center strip = three-piece mahogany. No seams = one-piece.

Three-Piece Maple, From 1975

Three-Piece Maple Neck: 1975 Onward (Norlin)

Around 1975, Gibson began transitioning from three-piece mahogany to three-piece maple on many of its electric models, the most significant neck material departure in the company’s history up to that point. Maple is a significantly brighter, harder, and denser tonewood than mahogany. Three-piece maple necks are easy to identify: the lighter color of maple compared to mahogany is usually immediately visible, and the two glue lines of the three-piece construction are present as on the mahogany version.

Dating IndicatorMid-Late Norlin EraFrom 1975Lighter Color Than MahoganyTwo Visible Glue LinesBrighter Tonal Character

If the neck wood is noticeably lighter in color than the body mahogany and shows two glue lines, you are looking at a three-piece maple neck, firmly placing the instrument in the post-1975 Norlin window.

Gibson Bridge and Hardware Dating: ABR-1, Nashville Bridge, Nickel and Chrome

The hardware on a vintage Gibson tells a surprisingly precise story. Gibson’s ABR-1 Tune-O-Matic was introduced in 1954 and remained the standard bridge for twenty years, but it changed in one important way around mid-to-late 1962: a thin retaining wire was added along the back of the saddles. No wire means pre-1962. Wire means post-1962. Around 1974 Gibson began transitioning to the larger Nashville Tune-O-Matic bridge, identifiable by the threaded metal inserts pressed into the body. Hardware finish is the second detail: from the beginning of Gibson’s electric production through 1965, all standard hardware was nickel-plated. In 1965 Gibson switched to chrome.

No-Wire ABR-1, 1954 to 1962

ABR-1 Tune-O-Matic: No Retaining Wire, 1954 to 1962

The ABR-1 Tune-O-Matic bridge was introduced by Gibson in 1954. The original design had no retaining wire. The individual saddles sat in the bridge base held only by string tension and could fall out if the strings were removed. This no-wire version is the bridge found on all of the most valuable golden-era Gibsons: the Les Paul Standards from 1958 to 1960, the original ES-335 from 1958, and every other top-tier instrument from the first eight years of ABR-1 production.

Golden Era, 1954-1962No Wire on SaddlesOriginal Tune-O-Matic Design

If there is no wire running along the back edge holding the saddles in place, you are looking at a pre-1962 ABR-1. One of the fastest golden-era confirmation checks available.

Wired ABR-1, Mid/Late 1962 to 1974

ABR-1 Tune-O-Matic: With Retaining Wire, Mid/Late 1962 to 1974

Around mid-to-late 1962, Gibson added a thin retaining wire to the ABR-1 bridge, running along the back edge of the saddles to prevent them from falling out. This created a clear dividing line: a wired ABR-1 means the bridge, and almost certainly the instrument, postdates mid-1962. The wired ABR-1 remained standard through 1974. The wire is thin and can be easy to miss on a dirty or corroded bridge, so clean the bridge carefully before drawing conclusions.

Mid/Late 1962-1974Thin Wire Along Saddle BacksOtherwise Identical to No-Wire

Look closely along the back edge of the saddles for a thin wire running across all six. Its presence places the bridge firmly after mid-1962. Its absence places it before.

Nashville Bridge, From 1974/1975

Nashville Tune-O-Matic Bridge: 1974 to 1975 Onward

Around 1974 Gibson began transitioning to a new, larger Tune-O-Matic design that collectors refer to as the Nashville bridge. The transition was gradual through 1974 and the Nashville bridge became standard by 1975. It is larger than the ABR-1, with wider spacing between the post studs. The single most important identifying feature is the threaded metal inserts that the post studs screw into, small cylindrical metal bushings pressed into the body.

1974/1975 OnwardThreaded Metal Post InsertsLarger Than ABR-1Norlin Era Standard

Look closely at the base of each bridge post where it enters the body: if you see a small metal bushing or collar pressed into the wood surrounding the post, that is the threaded insert that defines the Nashville bridge.

Gibson Case Identification: Dating and Authenticating Your Gibson By Its Original Case

A matching original case is one of the most overlooked authentication and dating tools in vintage Gibson collecting. Cases were manufactured by specific suppliers during specific windows, and the combination of exterior material, interior color, hardware, and construction details can independently confirm a production era. The most important case supplier for golden-era Gibsons was Lifton, whose “Faultless” cases accompanied instruments from the 1940s through the early 1960s. By the late 1970s the utilitarian rectangular “chainsaw” case had replaced everything that came before it.

Dating Gibson Guitars by Model: Les Paul, ES-335 & SG

Serial numbers will get you close, but on the most collectible Gibson models, the specific year of manufacture can mean a dramatic difference in value, and a serial number alone is rarely enough to confirm it. Gibson changed the pickups, hardware, finishes, body shapes, and construction methods of its most important models multiple times across the 1950s, 1960s, and 1970s. Each of those changes happened at a specific point in time, and knowing what was correct for a given year is what separates a confident identification from an educated guess.

The sections below cover the three models where year-specific feature dating matters most: the Les Paul, the ES-335, and the SG. Use the serial number tools above as your starting point, then use the model guides below to confirm and cross-reference what you find.

Gibson Les Paul Standard

The Les Paul Standard is the most collected and most studied electric guitar in history. Introduced in 1952 as the Goldtop and evolving through several distinct configurations before being temporarily retired in 1961, the Standard’s value is extraordinarily sensitive to the year of manufacture. A correctly identified and authenticated example from 1958, 1959, or 1960 (the “Burst years”) sits at the peak of Gibson’s golden era and commands prices that rival fine art. Understanding how the guitar changed year by year is essential for anyone trying to date or value one.

Gibson Les Paul Custom

Introduced 1954 · The “Black Beauty” · Gibson’s Flagship Les Paul

The Les Paul Custom was introduced in 1954 as Gibson’s premium version of the Les Paul, positioned above the Goldtop Standard in terms of appointments, finish, and price. Where the Standard was a working musician’s guitar, the Custom was designed to be Gibson’s showpiece: bound in multiple layers of binding, finished in ebony black, and fitted with gold hardware. Collectors call early examples “Black Beauties,” and genuine original Custom models from the 1950s are among the most valuable vintage Gibsons in existence.

Gibson Les Paul Special

Introduced 1955 · TV Yellow and Cherry Finishes · Two P-90s

The Les Paul Special was introduced in 1955 as a mid-range alternative to the Goldtop Standard, simpler in construction, lighter in weight, finished in a distinctive flat yellow color, and priced to be accessible to a wider range of players. Where the Standard had a carved maple top, the Special had a flat slab mahogany body. Despite its more modest original positioning, the Les Paul Special has become one of the most beloved vintage Gibsons among players, prized for its raw, direct tone from the two P-90 pickups and its comfortable lightweight construction.

Body Style and Cutaway Changes

The Les Paul Special went through a significant body design change in 1959, from a single-cutaway slab body to a double-cutaway body, making body shape one of the fastest dating tools on the Special.

Gibson Les Paul Junior

Introduced 1954 · Single P-90 · The Player’s Les Paul

The Les Paul Junior was introduced in 1954 as Gibson’s entry-level Les Paul, a stripped-down, affordable instrument designed for students and beginners. One P-90 pickup, a simple wrap-over bridge, a flat slab mahogany body with no binding, and a plain sunburst or cherry finish. What Gibson did not anticipate is that the Junior’s simplicity would become its greatest asset. The direct, unfiltered signal path from a single bridge P-90 through a minimal circuit produces a raw, aggressive tone that decades of famous players have sought out specifically.

Body Style and Cutaway Changes

Like the Special, the Junior went through a body change from single-cutaway to double-cutaway, but the Junior made this change in 1958, one year earlier than the Special. Body shape is one of the fastest dating tools on the Junior.

Gibson SG: Dating by Model and Features

Covers: SG Standard · SG Custom · SG Special · SG Junior

The Les Paul / SG Transition: 1961 to 1963

In 1961 Gibson replaced the single-cutaway Les Paul body with a new thinner, lighter double-cutaway design. This new body style was initially marketed under the Les Paul name. However Les Paul himself was unhappy with the new design and did not renew his endorsement contract when it expired in 1963. From that point the Les Paul name was removed and the guitars were sold simply as the SG Standard, SG Custom, SG Special, and SG Junior. The practical effect for collectors is that the most desirable early SGs (built between 1961 and 1963) carry the Les Paul name. The name on the headstock is a dating clue, not a different guitar.

Gibson SG Standard

Introduced 1961 (as Les Paul/SG) · Cherry, Walnut, and Ebony Finishes · Two Humbuckers

The SG Standard is the most produced and most widely recognized model in the SG lineup. Introduced in 1961 as the replacement for the single-cutaway Les Paul Standard, it established the visual template for the SG that continues to this day: thin mahogany body, twin pointed cutaways, two humbuckers, and a glued-in mahogany neck with a slender profile. The earliest examples from 1961 and 1962 are the most collectible.

Introduced 1961 (as Les Paul Custom) · Three Humbuckers · Gold Hardware

The SG Custom is the premium version of the SG lineup, the direct continuation of the Les Paul Custom onto the new double-cutaway body. Like its predecessor, the SG Custom is distinguished from the Standard by its multi-ply binding, gold hardware, ebony fingerboard, and (most visually distinctive of all) three humbuckers instead of two.

Gibson SG Special

Introduced 1961 (as Les Paul Special) · Two P-90s · TV Yellow, Cherry, and White

The SG Special is the direct continuation of the Les Paul Special onto the SG body, a mid-range instrument with two P-90 soapbar pickups and simpler appointments than the Standard or Custom. It carried the Les Paul Special name through the transitional period before becoming the SG Special in 1963. Among players the SG Special is prized for the raw, direct tone of two P-90s through a simple circuit.

Gibson SG Junior

Introduced 1961 (as Les Paul Junior) · Single Dog-Ear P-90 · Cherry and White

The SG Junior is the continuation of the Les Paul Junior on the SG body, the stripped-down, no-frills entry point into the SG lineup. One P-90 pickup at the bridge, a wrap-over tailpiece, no binding, no inlays beyond dot markers, and a plain Cherry finish. The Junior uses a dog-ear P-90, named for the small mounting tabs that extend from each side of the pickup cover, rather than the soapbar P-90 found on the Special.

Gibson ES-335 Family: Dating by Model and Features

Covers: ES-335 · ES-345 · ES-355 · ES-330

Introduced in 1958, the ES-335 was unlike anything Gibson had built before. By routing out two f-holes and gluing a solid maple center block through the middle of an otherwise hollow thinline body, Gibson created a guitar that combined the warm resonance of a hollow body archtop with the feedback resistance and sustain of a solidbody. The earliest examples, built in 1958 and 1959, are among the most collectible and most valuable vintage guitars in existence.

Gibson ES-335

Introduced 1958 · Semi-Hollow · Two Humbuckers · Dot then Block Inlays

The ES-335 is the model that defined the semi-hollow electric guitar category. Its production history spans from 1958 to the present, and the physical features changed considerably across that span. The 1958 to 1964 dot-neck examples are the most collectible. Dating any ES-335 accurately means looking at the cutaway shape, the inlays, the finish, the hardware, and the internal construction, not just the serial number.

The Cutaway Shape: The Single Most Important Visual Dating Tool

On guitars built from 1958 through 1961, the upper cutaway horns are rounded and full, with blunt, wide tips. Collectors call this the “Mickey Mouse ear” shape. On guitars built from 1962 onward, the upper cutaway horns are sharper and more pointed. The transition happened around 1962 and is consistent enough to be used as a primary dating reference.

Dot Inlays vs. Block Inlays

The ES-335 was introduced with small round dot inlays. In late 1962, Gibson switched to larger rectangular block inlays. A 335 with dot inlays and rounded horns is a pre-1962 instrument and represents the top tier of ES-335 collectibility. Block-neck 335s from 1963 to 1969 are excellent instruments, slightly less collectible than the dot-necks but highly regarded.

🔍 Rare Variant: Joe’s Note

This is one of the rarest ES-335 configurations I have ever personally encountered: an ES-335 fitted with a variant of the Maestro vibrola that is typically seen on Epiphone guitars rather than Gibson ES models. In all the years I have been buying and selling vintage instruments, I have seen exactly one of these. Whether this left the factory this way or was installed early in the guitar’s life, it is an unusual piece of hardware on this platform and a fascinating anomaly for any serious ES-335 collector.

Complete Dating Summary by Era

Gibson ES-345

Introduced 1959 · Semi-Hollow · Varitone Circuit · Stereo Wiring · Gold Hardware

The ES-345 sits in the middle of Gibson’s thinline semi-hollow lineup, above the 335 and below the 355. It shares the same semi-hollow body construction and two-humbucker layout as the 335 but adds three significant features: the Varitone circuit, stereo output wiring, and gold hardware throughout. Introduced in 1959, it’s less commonly seen than the 335 and considerably rarer in the vintage market.

Gibson ES-355

Introduced 1958 · Top-of-Line Semi-Hollow · Maximum Binding · Multiple Hardware Options

Sitting at the top of the thinline semi-hollow family, the ES-355 carries the heaviest binding, the most ornate appointments, and the widest range of hardware options of any model in the ES lineup. It carries five-ply binding, bound f-holes, a bound and inlaid headstock, block inlays, and gold hardware throughout, and was available in both mono and stereo versions. In terms of top-tier appointments, it’s the ES equivalent of the Les Paul Custom.

Gibson ES-330

Introduced 1959 · Fully Hollow · P-90 Pickups · 16th-Fret Neck Joint

The ES-330 looks almost identical to the ES-335 from a distance, but it is a fundamentally different instrument. Where the ES-335 has a solid maple center block running through the body, the ES-330 is fully hollow. It also uses P-90 pickups rather than humbuckers, and the neck joins the body at the 16th fret rather than the 19th fret on the 335.
