Seems to be a great tone but dude, the low end is RUMBLING! I'm guessing it is the kick drum because the nature of the rumble indicates, to me atleast, that it's something more percussive than a bass guitar/guitar. The bass guitar could contribute to the rumble too I suppose, but I would start looking at the kick drum first. If you can strap a Dominion on the kick and maybe pull down the sustain a little bit, you could shape the sound so it keeps all the nice transient but dampens the damn rumbling sustain
