Re: UV777PBK wont stay in tune?
This isnt an answer to your problem, just sharing mine with ya. Every Universe, or RG I ever owned had a staying in tune problem. However, mine was limited to just the g-string. I use to strip my lock screws, thinking I wasnt tightening them enough. I would bend the string, and I would have to hit the trem bar right afterwards to pop it back in tune. Every single one of my Ibanez's did this. I finally figuered out that there was this weird balance of how far the fine tuner had to be screwed downward. If it was up to high, I could never get it under control. I eventually figured out that, after I put new strings on, tune, lock, I would go nuts bending the strings. The g-string would always be way flat afterwards. I would just unlock it, bring it back up to tune, then re-lock it. The fine tune screw had to only be up...........maybe.......4 threads or so. Ive always written this problem off as a "personal defect".
But thinking about your problem..............just curious.........how many springs are on the trem?
