Anybody knows what's the proper nut action for a FR tremolo? I leveled a Randy Rhoads for a friend and it started with .030 which I believe was too much any way. Now I got .040 spacing and it's a bit uncomfortable. I'll be lowering the shelf itself since there's enough material, but I don't know what should my base be. With a bone nut I usually go .010 electrics and .020 on acoustics. If I get this one to a half meaning .020'' at the first fret I'm gonna be happy.
