NOTES ON SERIAL NUMBERS:
MM = month (01 to 12)
Y = last digit of the year (ex: 1992 = 2)
NNN = production number 000 to 999 resetted every year
- year "7" can be 1987 or 1997, "8" can be 1988 or 1998, "9" can be 1989 or 1999! You have to look at the models in production that year.
- lot of old esp's does not have any serial on the back of the headstock. If you are lucky you can find a serial written on pencil where the body is bolted to the neck (or in the neck also) or in one of the pickup cavities.
