Can't read a digit? Type ? in its place. Looked-up serials are kept, never tied to you. How it works

Your answer appears here

Type the serial or code from the instrument. We read it as you type.

Cross-check with a pot code

The number stamped on a potentiometer inside the guitar. It dates the part, not the whole instrument.

How sure is it

Every result carries its confidence. Treat the year as a strong guide, not proof: a serial can be replaced, a neck and body can be from different years, and reissues copy old numbering. For anything that matters, confirm the year against the neck date, the pot codes.
