I just got one and I must say, if any of you get the chance get yourselves some sort of preamp. This thing rocks. It's a discontinued model from BBE that I bought off a friend for 50 bucks. It's fairly simple to hook up, and it beefs up my lows, brightens my highs, and generally cleans and tightens up my sound. I just put it in my rack and I can't wait to try it out friday at the show. I'm in love. heart
