would this sound like muck? i want to upgrade, im looking for alot of mids and distortion. this sounds like the best route, but would i have trouble with lows? i could like, get a 1x15 to send the lows to. but I might have trouble powering it, because I'm going to have to get a low powered head to not explode the 4x12, right? lots of lows arn't really that essential to my style, anyways.
