I’ve been playing through a Backline 600 at a rehearsal studio and love the tone I’ve been getting. Although I’m more or less a tube amp guy, I’d like to get a lighter weight alternative and backup amp. Curious what the best sounding GK head might be. I had a Fusion 550 at one point and frankly didn’t like it. I’m thinking about maybe a 700RB-II or maybe a 1001RB-II (and don’t know the tonal differences between the two). Thoughts?
