B-string buzzing at trem - How do I get rid of it?

[bduersch]

On the RG-570 I just picked up, the b-string buzzes obnoxiously at the trem. It buzzes at every fret, and (of course) buzzes more obnoxiously the harder I hit the string.

Anybody know how to remedy this? I've fixed fret buzz on a few guitars before, but I've never had the buzz at the other end of the string.

Thanks,
