So I've been experimenting more with the non-floating floyd-rose trem on my new Wolfgang Special. I have an annoying problem now. After I do dive bombs, often some of the strings will remain slightly sharp. Yesterday I had lowered the string hieght on the low-E side of the trem, and this made the problem worse - after a dive bomb, *all* strings would come back more than 10 cents sharp - enough to be noticeable (100 cents = 1 semitone, 5 cents is the threshold of what most people can discern). If I tugged or bent one of the strings, they would all magically return to correct tuning. After raising the string height on the low-E side back up again, the problem is now minor, but still detectable with a tuner. Now, after a dive bomb, the G and D strings seem to be returning about 4-5 cents sharp. Again, tugging or bending one of these strings returns the strings into tune. This being a non-floating trem (and a brand new one), I am wondering what the cause could be. Any theories? Could lubricating any of the parts on the trem help? Thanks!
