what are somethings i can do or replace to be able to use my whammy bar decently aggresively without the guitar going out of tune?
get a LSR roller nut is the only thing i can think of. Oh, and locking tuners
im still trying to figure it out
On my two mian Strats I use locking tuners & a trem-setter. The rosewood board has a Graphtec nut and I use nut juice on the maple necks corian nut. Works pretty good for me.
Graphite bridge saddles+roller nut/graphite nut+locking tuners
