So yeah, I have a drummer who thinks he knows tone I have a VHT UL and it pretty much slays most amps in it's path. At my house it sounds killer. At my friends house it sounds even better. I have yet to use this particular amp on stage yet but at practice, in my drummers concrete basement it sounds like complete shit and I can see where he is coming from when he says my amp sucks. But he doesn't believe that it is his basement that sucks So my question is, how can I get it to sound better? Foam panels on the wall is the only thing I can think of. It is an all concrete basement.
