Right now I'm using a Peavey TNT 115 and this thing just sounds like a garbage can. It's loud, but it has like no tone whatsoever. Any ideas what I could get that actually has a nice sound with lots of growl? I play fretless and the amp I have currently makes it sound like poop, i have mwah but I want MWAHRAWRGROWLDOOMDEATHKILL. Know what I mean?
