I went to see a prog metal band the other night, and they had 60 watt tube amps, in a room about 25x50, with 15 ft ceilings. They were so low, that the excitement factor of a metal band was simply not in the room at all. They played well, and that did a lot for them, but the tones were crap. The sound man had mics on all the amps, and they were set on around 1.5 - 2 on their volumes. Sounded like cans full of angry bees. At any point during their two sets, the drummer was in real danger of overpowering the PA. So, when do you guys feel that quiet is just too damn quiet?
