Mine doesn't stay in tune that well. I've had a number of setups by different techs, messed around with the nut, the saddles, frets, etc.... it plays well, and stays for a few songs then starts to go flat a bit. It's a standard with kluson tuners. I'm thinking the tuners might be the culprit. I replaced the tuners to locking ones on my strat and it stays in tune no matter what abuse I put it through. Has anybody had any luck with locking or more stable tuners on their gibsons? If so, what do you recommend. I would like something that can retro fit with any modifications.
