I know lots of people are tube lovers, and I admit that they are hard to beat, but I have done several gigs with the deluxe tonemaster blonde and it performed admirably. I have yet to try the twin in a gig situation, but will stick my neck out here and say that in a band situation, noone can tell its not a tube amp once the drummer and bass and vocals are all blasting away....and they weigh half the weight , and have a DI out and attenuators to get the best sound at the right volume. Im impressed.
