So... I just put a Bigsby B5 on my Les Paul Special (Flat Top). Guess what... I have tuning problems. I hear the occasional "ping" at the nut and I will deal with that by making a Slipstone replacement nut. That should help the nut-end of things. I am planning to put on a roller bridge as well. I see two that look interesting from a place called GuitarFetish. One is a tunomatic type roller bridge . The other is a Wilkinson roller bridge. Any suggestions on which may be better?
