Lately my guitar has frequently been going out of tune. I have a PRS SE Custom 24(bought in new 7 moths ago), i don't see what seems to be the problem. It mostly goes out of tune on the G and B string when do bends on the strings or use the whammy bar. I find myself re-tuning all the time. I was recently playing at my church, did a little whammy bar usage, and my strings went out of tune, leaving me out of tune the whole time I was playing. Is there anything I should do to make sure it never goes out of tune on me again?
