overkill you watts(amp) and you cab...meaning....iof you want to be hella loud and want break up........get a pedal that does it for you alla bigmuff..or a ibanez tube screamer...yes a cursed guitar pedal........they sound just like a amp about to explode from being on ten.....also have a lil...empashize lil hed room in you cabs...me personally i run 2 300 watts amps to a 2 300 to 400 watt cabs, (a gk to a 4x10, and a old peavey to a 1x18..awesomeness to an extream...)and only turn the volume to about 6 or 7 on both at the loudest shows......or ill use a big muff to get that exploding sound aswell...simply becase a tube scremaer or a big muff are 50 bucks each....my rig is over 1500 dollars if somthings gonna blow I want it to be the cheap ass pedal
