Wasn't sure where to post this, but I figured the PTC might be a good place.
Recently I've been noticing primarily the G string on my Custom 24 will make a small click or tink sound either when tuning, bending or using the trem arm and the string will go out of tune slightly (and only sometimes). I say primarily because I sometimes get it with the B string as well, but rarely get it on other strings. It is somewhat annoying and a bit troublesome, being that I love the trem (and love being in tune...). I've always been impressed with how well I've heard/seen PRS guitars stay in tune and hold up even in the most righteous whammy dives. In particular some of Chappers and the Captain's videos in demo'ing some PRS axes have them literally flattening the trem and strumming loose strings, after which immediately playing chords that were perfectly in tune.
My main questions would be: 1) Is there something I'm missing when changing and stretching strings that is making staying in tune more difficult, and 2) how can I address this nut binding issue (as I believe it is, I've done some googling and quick internetz research)?
