I play a Shuttle 9.0 and I think its a killer little amp. Its simple, but has features I like. Aux in, headphone out, etc. Maybe, i'd like something with a little more power someday, but then again I haven't tried it at 4 ohms yet. I also play a 2x12 and a warwick fortress.
Or you could work out some kind of a dolly. Or put wheels on your cab if you dont already have them.
