i recently got a new strat to replace my ill-fated beck strat. this one has a 6 screw bridge and i really miss the 2 post bridge on the beck. the 6 screw just doesn't feel right/as smooth. any advice on dealing with this or tips on making the 6 screw bridge move more smoothly? can screws be removed? and while i'm at it, just remembered that i've got a loose whammy bar. even when screwed in all the way, it rocks a little bit in the hole.
