I am a relatively new guitarist, and have a guitar that up until 20 minutes ago I was telling people was a USAC (thats what it said on the pickup, and I am a newbie).
Thanks to some web research, I found out what I have is a 540r
from 1989. Though, I noticed my serial number
on the plate has no letter in it, it is only numbers. I thought I read somewhere that these guitars had serial numbers that started with an F. Does this mean anything that mine doesn't? Is this just another beginners observation?
