I have a Mesa Single rectifier and a 4x12 rectifier cab. due to the size of my room the back of the amp is about 20 inches away from a wall and my entire room is tile. i get a very bright harsh sound at loud volumes. if there anything i could in the back of the amp to help sound quality ? Thanks for the input.
Take it out of the tile room? O.o Or maybe re-EQ it for loud volumes. Or set it on a piece of carpet. Try beam blockers too (google it).
Then there's this band called Slice The Cake...

Bunch of faggots putting random riffs together and calling it "progressive" deathcore.
Stupid name.
Probably picked "for teh lulz"

put up some egg crate? anything to dampen the sound should help, rugs, carpeting, etc.
