MARKBASS Anybody ever play this amp? I think Guitar Center is the only distributer in the States for Mark Bass. Anyways, I picked this up last weekend, and I can already say that this is the best bass amp I've played through. It weighs 6 lbs, and pounds out 500 of watts of thunder all for $600. I'm currently using it with a 1x12 at home, but it sounds just Godly through a 4x10, or even two of the 1x12s. It does not do dirty, so for those who are after the Ampeg sound, this won't do without a pedal, or a preamp in front of it. But when it come to punch, GK and SWR have nothing on Mark Bass. It's very clean and clear. Perfect for all genres except for metal. I haven't run a 5er into it yet, but according to forums, these handle the Low a/b just fine. Anyways, I highly recommend it to anyone looking for a great light weight amp that sounds good.
