Hello, two weeks ago I bought a very slightly used, virtually new PRS SE standard 24 (my first PRS, so I'm also a PRS forum newbie..), and the first couple of days I had it, I couldn't put it down. It played beautifully, and I was also very impressed with the tremolo, it seemed I could do even "Floyd Rose"-type tricks with it, and it still stayed (almost) perfectly in tune. I also used it for a gig last weekend, but after that, I hadn't played it for a week. When I picked it up again and played it now, the trem seemed to have changed drastically, it doesn't stay in tune anymore, and it also doesn't seem as smooth as it was only a week ago, it seems a bit stiffer in a way. I tried to unscrew the trem arm and put it back, securing it was sitting tight, but that didn't make any difference. If I push down on the tremolo, it goes flat, if I afterwards pull up on it, it goes sharp. Or it seems that it has two different "zero positions", one when I go down, and another one if I go up, and there's like a 1/4 note between the two.. What has happened to my trem, it wasn't like this only a week ago..?
