I recently purchased a "frankenstrat" from a local guitar store. I'm using it to improve my skills on doing setups, replacing/cleaning hardware, etc. (Yes, I like working on guitars...). There is not a serial number anywhere to be found on the guitar. However, I did find a signature on the base of the neck and a sticker on the plate (pictures attached). Anyone recognize any of these? The guitar dealer thinks that the sticker was commonly found on 1990's MIJ guitars but I thought that I would share to see if anyone has seen these before. Thanks!
