I have always heard about the TB or TBX models but never saw one. Sam Ash had one today so I thought I would try it out. It was amazing, especially compared to the CC model w Greenbacks. I own a Don Butler modded AC30CC head and it is a great amp but I think the TB model comes very close and is better in a few ways. It is very hard to compare heads and combos though. Anyways, what is a fair price on a TB model? This one was not in great shape, seemed a bit noisy, and it had Weber Blues in it. Not sure if it was a TBX or TB (if that matters). They wanted $1,000 for it. It sounded great and vintage and full. But I dont know if it is worth that.
