What's a good light weight alternative to a Fender Twin? It's my main gigging amp at the minute but the thing breaks my back every time I have to lift it and I'm getting a bit fed up with it. I like the sound of it and it works for me because I play a lot of blues stuff. But man, it's like trying to lift the front end of your car up every time. Any good alternatives that have a lot of clean headroom like a twin, but is considerably lighter in weight? Thanks.
