So, my Mono Block II came in the mail today, it looked a little beat, I didn't mind, I hate things to be all shiney and new anyway. First thing I notice, "Damn, this thing weighs about 60lbs, at least." Maybe more, I'm a bad judge of weight So I take it to my guitarists house, because that's where my big Sunn cab lives. I throw it on top... well, I drag it on top, this thing is heavy and hard to "throw." But I gave it a shot. It sounded great! Heavy, Clean, I'm very very excited. The main volume pot is a bit noisy, I'll probably get that fixed. I'm in a doom metal band, and if you know anything about doom, the question is... HOW LOUD CAN IT GET?!?! To answer my question, I cranked it. Remeber how I said this thing was heavy? IT WAS BOUNCING OFF MY CAB AND STARTING TO WALK OFF MY CAB!!!! Luckily I stopped before it finished. DAMN THIS THING HAS POWER!! And it sounds perfect! THANKS SMASH for the heads up on this awesome awesome head!
