I've had my PRS Custom 24 for several months now and I adore it, however I have run into SEVERE tuning stability issues. [br] To combat this I bought locking tuners, which helped but didn't do a whole lot, then I got it set up by the most highly rated luthier in my area. [br] After this my tuning stability was extended to about 2 songs if I did NOT use the whammy bar, and 1 if I did. Before this the guitar would make it maybe 35-60 seconds before going out of tune without the whammy, and as soon as I even touched the whammy, it was out.

So, it's certainly better, but it's still irritating, I wouldn't expect a 1000 dollar guitar to have this many issues, especially after 250+ Dollars on upgrades, would anyone have a suggestion?

Any help is appreciated even minor stuff. [br][br]

side note: I am also using high quality string, which I put on last week.
