When I push the vibrato bar down on the (non-floating) floyd rose on my Wolfgang special, the tension on the lower strings relaxes much more than on the upper strings. For an extreme dive with the low strings relaxed to totally floppy spaghetti, the high E string still has tension and the pitch has only decreased by about 4 semitones. Is this normal? Should I adjust the relative tension between the two springs at the back? *edit* Just looked at the bridge again, and i noticed that in the normal position (whammy bar not depressed) the high E side of the bridge sits higher on the guitar than the low E side. It appears that the "post" of the bridge on the high E side is screwed in further, so the bridge is sitting lower on that side. This probably accoutns for there being less release on that side when I dive. Is this a proper setup? Are these post heights adjustable?
