My three bolt seems to be giving me problems. The neck shifts around. Any ideas? Should I put a 4 bolt on?
i would try doweling the holes in the body and neck first and re-mounting the neck. ive got a late 70's body that ive got a 4 bolt neck on. the body was drilled for the 4 bolt neck but there was a lot of slop. doweling fixed the side to side play moreso than shims on either side of the neck pocket to fill the gaps.
