I need a new amp, because my band is starting to play bigger gigs. Right now im using an SWR 60 watt stack and it just isnt cutting it. I have $700 to spend on a head, and about $250 to spend on the cab (im going with Avatar). Which of these two amp heads is better? The Ampeg B2RE or a Gallien-Krueger 700RB II? I played them both at GC, but the guy that was "helping" me was really terrible. He would only let me hook up to a used brandless 2X10 cabinet. It sounded horrible. So what are your experiences with the heads? Thanks in advance.
