I recently bought a Joe Meek threeQ. I don't know many of the technical aspects, but I did want to point it out to you folks. I've been looking for a pre-amp that accepted XLR in's and had phantom power, and some EQ, primarily for recording my upright with condenser mics. I've not used the item in a live setting yet, but that should happen in the weeks to come. http://joemeek.com/threeq.html They retail for $299, but you can find new for $200 or less.
