I was getting a bit of a metallic rattle on my ACCSH, and it seemed to be coming from the bridge. Everything seemed to be set up properly, so I decided to borrow a vintage 3-saddle bridge from a friend to see if there was any difference. The rattle went away, but I was pretty surprised that the guitar warmed up as a result of the bridge/saddle change. I didn't expect that at all. I like the tone enough that I ordered a Barden bridge with compensated saddles.
I believe I found the source of the rattle. Once I got the original bridge off, I noticed two height adjustment screws were just a tad shorter than the other screw on that particular saddle. When the saddles were pushed together, I think those two screws were just far enough off the bridge plate to resonate/rattle. Operator error, not an equipment problem!
In any case, here's my ACCSH with a vintage bridge. I like the look!
