They emailed me back pretty quickly suggestion I try the 'Blue Velvet' bridge model.

I just thought i'd see if anyone had tried it before I go and buy it. Obviously it will sound different with every setup people have, but at least I can check how clear the sound is and how responsive it is. Oh yeah, and how much humming the thing has...
Anyone with any suggestions,comments?
