Earlier this year, I purchased a used '05 SAS for a great price. I spent quite a bit of time fixing the setup, as the trem had been screwed right down to the body. No matter what I did, i couldn't get the trem arm into the trem itself. Finally, I got a brand new PRS trem (didn't trust the previous owner not to trash the knife edges, and in fact he had) yesterday and took the old one off the guitar and apart. Inspection of the insert itself shows no obvious reason why the arm will not go in. There is something internally wrong, but what really surprised me is that the trem block is cracked and split open in 2 places where the insert fits in. I am at a loss as to how someone could cause that much damage.

The new trem has the brass block and string contact points on the saddles, so I am looking forward to hearing it when I have it set up again. I'm also taking this opportunity to drop in a set of 53/10 pickups before I use my last set of Thomastik Blues Sliders on it.
