I've got a Peavey Wolfgang Special with the fixed-bridge floyd rose. The problem is whenever I use my whammy the whole guitar goes flat, more so the G string. Last time this happened the bridge was too far on one side, so it was an easy fix, but this time it seems to be even with the body. Whats the problem here?
since it is a flush mount floyd, tighten the spring tension on the trem a little and see if it gets any better.
Check if the nut is loose.
