The other day, I was trying out a ProCo RAT 2, and the guitar I played through it was a Jackson guitar with a Floyd Rose. At first, I was able to get it into perfect tune, so I did a divebomb. After the divebomb, the guitar went out of tune, which doesn't happen to me usually with a Floyd Rose. I tried tuning it, but the G string got to a point where it was still way to sharp and, and the fine tuner couldn't go lower in pitch anymore. What would be the best thing to do next time this happens, and is there any way to deal with it at a live show?
