Used on a SBMM Sub Ray 5.
Pros: More compressed tone, smoother high notes, absolutely no rattle, rock-solid bottom end, reminiscent of a Spector. Easy to load strings.
Cons: Less growl, the saddles are too tall and the instrument will need either a neck shim (easy), or the saddles need to be filed down (annoying). Increases the amount of low end, which can take away from the character of the instrument.
Quality: Overall very good. However, intonation travel, if the saddles are at the very front of the bridge, is very clunky, because the channels are too narrow. However, the intonation range is very generous, and only the "nice" part of the channels can be used.
Summary: A nice bridge if you want more earth movement and less growl.
