I’ve had a Charvel San Dimas for about 6 years now, and when I first bought it the strings would stay in tune no matter how crazy and out of control I got with the whammy bar. Recently though it seems like the strings will go out of tune pretty quickly with anything more than some vibrato with the bar. Dive bombs definitely throw them out of tune.
My guess is that some of the guitar’s hardware has aged and is no longer doing its job, but I can’t figure out what it would be. I don’t see what could be wrong with the locking nuts or the saddle clamps, as their only function is to clamp down tightly. Could some wear and tear to these parts cause slippage? I’m curious if anyone else has solved a similar problem. Thanks!
