I read endless posts everywhere about 600W here and 1000W there. Admittedly I have an 800W amp that I use at gigs, but lately I've been dragging my backup amp which is only 200W to practices. Low and behold, the smaller amp cranks out enough power to easily keep up with the drums and screaming guitars. Anyone else notice a similar phenomenon? Are we simply fooling ourselves into believing that we need the behemoth amps?
