peak power... heh...
just FWIW---- there is NO WAY to produce 3600 watts of output from *anything* plugged into a 15 amp outlet. not even for a millisecond (peak power). unless we are talking about a step-up transformer or something (not an instrument amplifier), and even then i am not sure how that would add up.
15A * 120 VAC = 1800 watts (from the wall). and while i am neither a scientist or an electrician, i am 99.99% certain that "continuous" draw needs to be at 80% or less of the circuit's maximum rating to be safe and reliable. wonder what the bugera says right next to the power plug socket?
