Any opinion or experience with the polytone? I've heard it's a killer jazz amp, which all I want/need right now. I am looking for a relatively small jazz amp that I can carry by the handle in one arm while carrying my guitar in the other (I'm doing a jazz ensemble at NEC, and I need to transport my amp around, and I would rather not make two trips up and down three floors for obvious reasons).

If no one knows anything about the polytone, any other suggestions? I've heard good things about the Fender Blues Jr., but I'm not so sure...
