Anything else, you'll make small compromises. And those compromises will either work for you, or not. But jumping to conclusions is usually foolish. I would view installing a Core or Mann trem as a very small compromise if that's what it took, and to say it's polishing a turd is downright wrong. No PRS has been a turd. Time and experience have proven that over and over.
Relaxxxx. Turd polishing is just a saying. I wasn't calling PRS guitars turds. It just means taking a cheaper guitar and modding it to a higher spec.
I'm regards to the trem. Its not a direct swap. The pivot screws are not the same thread and not an exact fit for the SE screws. They are a TAD bit looser than they should be. Most people won't even notice. But, the correct way to swap the trems is to fill and redrill new pilot holes for the new pivot screws.
