havent done it yet.my guitar wont be back till sunday.then again,i may not try it then cuz ive got a performance on tuesday.but ive the .052 gauge strings all waitin and all.after tuesday's performance im gonna try it again.im pretty sure it'll work out right.cuz i THINK i know the prob.firstly,i tried tightening the trem springs WHEN the strings were still on and TIGHT.secondly i did not change the strings one by one in the sense that i replaced the strings one by one all right,BUT i didnt tune them first before moving to loosen and replace the other string.
