Where to Find the Serial Number on a Guild Guitars Guitar
Guild acoustic guitars feature an oval or rectangular paper label glued to the interior back wood visible through the soundhole, showing model and serial number.
Solidbody electrics (e.g. Starfire, Polara, Bluesbird) and many vintage acoustics have the serial number stamped into the back of the headstock.
On early Hoboken and Westerly models, the serial number is also frequently stamped directly onto the wooden neck block inside the guitar body.
