^ I agree that brass may increase sustain and note clarity. My McCarty came with the adjustable PRS bridge, which I'm pretty sure has brass saddles and I love that guitar. However, in theory, the one piece design on OP's guitar increase sustain by not having moving parts. I haven't tested it myself, but it seems plausible to me that the increased sustain of using brass saddles could be matched by using a solid piece bridge. Have you A/B'd them side by side? At this moment I can only make conjectures, but if you have actually tested the difference, I'd be interested in hearing what you found. Anyway, MannMade stuff are awesome. The adjustable PRS bridge also works pretty well for me. However, since the buzzing is being caused by the back of the stoptail being risen at the back over time, I don't see how swapping the bridge will address the issue permanently. I think either the locking studs or the washer solutions will likely directly address the issue at a considerable lower cost less than swapping the entire bridge. Both of these solutions should prevent the bridge from creeping up over time. Also OP expressed that he did not wish to mess with the sound of the guitar, but, if possible, address only the buzzing issue. Thus, I think the less parts he changes in his guitar, the more likely OP will achieve what he's after. I know you were just replying to another comment, so I didn't mean to suggest that you were suggesting OP to swap his bridge. I just thought It'd share my thoughts, which might help OP save some money he doesn't necessarily hove to spend to fix the buzzing on his guitar.
