Hey all, I just picked up an '06 Fender Classic Player 60's Strat, used. It needed to be cleaned up a bit...grunch on the strings, some rust on the pole pieces, dirty fretboard. So I stripped it down to parts, scrub everything down and polish the body...and I find two slips of thin card stock as a "shim" under the neck. So my question...does Fender do this? Or was someone doing some monkey work of a setup on this?
