Free guitar appraisal app
A free guitar appraisal app helps identify whether a guitar is a common player instrument, a vintage model, a modified piece, or a provenance-sensitive item that needs deeper review.

Start with maker, model, serial number, body style, headstock logo, pickups, finish, case, and condition. A guitar with verified provenance, original parts, or a desirable vintage spec should not be treated like an ordinary used instrument.
Auction records are market evidence, not a final appraisal. Condition, authenticity, provenance, originality, modifications, playability, and demand can materially change value.
Photo checklist
- Full front and back, headstock front and back, serial number, logo, neck joint, bridge, pickups, knobs, tuners, case, labels, and electronics.
- Close-ups of cracks, finish checking, repairs, replaced parts, routing, pickup cavities, neck angle, fret wear, and case labels.
- Receipts, repair invoices, certificates, stage photos, letters, or any ownership documentation.
