I picked up this P-Bass for a song and I sing like crap. The pencil neck date is 8-20-82, and its also stamped Torres and FRR 20. There is no serial number on the neck plate or neck. The pots are numbered R1378227 which would date them to 1982, the same as the neck. I can't figure out why there is no serial number on the guitar unless the neck plate was replaced with the scroll "F" plate that is currently on it?? Anyone know if this is the Fullerton reissue of the 1957 P that Fender put out in 82? Any input on no serial number?
