Locking nut doesn't lock!
This is really odd, bought a nice secondhand RG550 and noticed I couldn't lock the E/A nut clamp it started to tighten then would go loose again.
Me thinks knackered thread in the nut...anyhoo noticed the other 2 clams could be tightened BUT the machine heads could alter the string tuning when clamped (??)
Never seen a clamped top nut that allows the machine heads to alter the tuning - very strange.
So I bought a replacement nut, fitted it and now I can lock all 3 clamps at the nut but the machine heads still can alter the tuning no matter how tight the clamps are locked!!
Never experienced this before, on the JEM the machine heads make no difference once the nut clamps are locked but on this RG550 even a new top nut assembly doesn't stop the machine heads altering the tuning.
Why is this, can/does it need to be fixed and if I use the trem does that mean the tuning will be out??
