tuning problem: neck shift or truss rod?
I own many RG350's, and most have excellent tuning stability, but one has a strange issue -- while I'm playing I can sometimes feel a shudder go through the neck and then the guitar will be out of tune. I have swapped out the tremolo and the posts and am 100% certain they are not to blame (the studs are locked, and dropping in several different tremolos does not fix the issue). I have taken apart the whole guitar many times to look for issues. The nut is solidly attached, so that's not shifting. I've taken the neck off, cleaned out the neck pocket, tightened the neck screws, etc. Something is shifting during playing, usually after an extreme string bend (which increases the string tension momentarily). The screw holes in the neck look fine. When those screws are tightened it all seems solid. These are AANJ necks, so there is no threading in the guitar body for the neck screws---just a metal washer set into the wood at the heel. I think that either the problem must be with the neck screws shifting in the body/heel, or that there might be something amiss with the truss rod. The truss rod is tight.
