omg does it distort! it sounds massive. i ran it into my bassists two ampeg 4x12's and my studio pa head into my 2x15. let's just say it is a wall of sound. i jumpered the channels on the coliseum. it def has enough gain without doing that, but i did it anyway, just to see. hahaha. the studio pa with the winged c 6550's has all my midrange, and the coliseum with original kt88's fills out the bottom and gives a bit more top end. very full tone. can't wait for our show friday!
