Hi guys, so I am having extreme tuning issues with Edge pro Trem of my Ibanez RG1570. I bought it used, and it looks like the locking saddles at nut are actually wore off a little. The fine tuner on E string is not being effective, and in overal use, guitar doesn't stay in tune. You know using the trem a little bit with more float, get's A, G, and B strings out of tune by a little every time, and a dive bomb just screws it all up. Do you have any ideas which strings should I use, which brand makes nice replacements for locking nut, and the springs are changed yet, where can I find nice springs?
