I have both the B1 single space rack amp and the 2-12 cab with 3 rack spaces for the gear. It works and sounds wonderful. I don't have a lot of "time"on the tubes either, neither piece has been gigged, and both are almost like new. Actually, I would be willing to sell them, if anyone is interested because I have other rigs, that are more portable, and the cab is pretty heavy because the speakers have massive magnets and the wood in the cab is heavy. I live in North Carolina, near Greensboro, so give me an email or reply if you have any interest.
