Problema en puente y Bigsby

Alguien escribió:

I asked a pro about this (probably one of the best guitar techs we have here in Athens Greece) and told me that the moving of the bridge is normal, since the bridge screws (or pins -don't know what is the right word-) are stable and the tuning is not affected there's no reason to replace it, and that it will not damage my guitar. He told me though that a roller bridge would do better with the bigsby, but I have not to hurry for an upgrade... Later I called another guitar tech I know and he told me the same thing, and that he has a Gretch which has as bridge that is also moving when Bigsby is used....
