Condition And Originality
Plectrum guitars have a different neck and scale from tenor models. Confirm the full factory model, original neck, bridge and string arrangement. Conversions and replacement necks need separate valuation. The OM-18P range is approximate because the model is scarce.
For the broader comparison, read how repairs and changed parts affect guitar value. If the finish has been changed, the refinish value guide explains full and partial work and why an acoustic needs its own assessment.
