A lot of people say that the teal amps and the early Transtubes are pretty much identical for cleans. I've never played through a 1st series Transtube so can't say for sure. The Supersat (TM) circuit on the teals has its fans too. I've always been able to get decent tones out of them at jams and the like. I'd take a teal stripe over the current "big badge" versions for build quality, not to mention a real reverb tank.
