RG550 and Edge problems with the Edge trem, please advice
I've got an old RG550 (1989, Edge trem, basswood body, one piece maple neck, rosewood fretboard, more black than a Spinal Tap album, Gotoh tuners, old style block heel, pickups changed to Seymour Duncans). I recently put .010 strings on it (that is, it had 10s on it but I put on new ones since the ones that were on it previously were worn) and adjusted the trem so that the notches on the sides are parallel with the body. The action is fine and intonation correct, and the only parts that show any noticeable wear are the nut lock pads (the strings have scratched of the paint where the strings lie underneath the pad). The strings are also properly stretched.
Anyway, the thing doesn't stay in tune for very long, I have to keep retuning it with the fine tuners pretty much every day (I play about 1-2h a day) or even more often.
Then I noticed that the trem isn't like suggested on Jemsite, but it's a bit higher from the body (and it's not parallel to the body if you look at the top of the saddles). But I had to screw the springs (3 of them) all the way to the back to get it in position where the notches were aligned with the body, so I can't move the trem further back. What do you suggest I should do, get new springs, get more springs or what?
