Locking nut wierdness
hey guys, I took my locking nut off on my RG520 around 3 weeks ago while doing a thorough cleaning of it. Well right now my problem since i put it back on is, the bass-side screw is further in, you can't really visually tell, but the treble side one is sticking out more just enough for it to be annoying. Each of the screws had washer under them, but the base side washer had kind of a star shape hole on the inside, instead of just round, which I though was weird.
Did I screw up my nut, is this normal? the nut also has a bass side shim (in addition to 2 full shims). Tell me what might be up with it.
