I need a small head for my Ampeg 410he --(8ohms). I'm doing some smaller clubs that it's stupid to bring the SVT to.I thought a small rig would be nice to have also. I played though a GK backline 600 that was nice,a bit weak though. 3 pro's go for too much.Maybe a b2r,b2re,(what's the difference?)I like the Ampeg tone I suppose.Old school bottom. Opinions?
