Hey i have a fender classic player 50's strat, it has gotoh locking tuners but when i use the trem it goes way out of tune, normally the b and higher e strings go sharp. Ive noticed the trem block is floating quite high, could this affect it? also the trem has 2 pivot screws not the usual 5 or 6 fixed place ones on a strat, mine are more like the pivots scres on an FR
It's cause your using a non-locking tremolo, by 60s Strat cdn do the same thing.
what the guy above me said and try nutsauce or graphite on your nut it helps a lot for staying in tune
