Lord's got a point, if what you do is lots of string bending and vibrato, but not any tremelo arm stuff, the best solution to tuning (and a good tone ijection) would be to ditch the tremelo and stuff it full of wood or brass or whatever. The other thing is that you should look at getting something like those graphtech saddles, and a new nut. A small investment like that will do wonders to a guitar fitted with stock equipment that is generally not nearly as goood as specialist stuff.
