These are in stock on the Carvin website now. I haven't played a B1000, but FWIW I have an older B800 which is almost the same power (300W @ 2ohm, 500W @ 4 ohm, 800W @ 2ohm), and I wouldn't trade it for anything else. If someone stole it or it somehow got destroyed, I would probably replace it with the B1000 if I couldn't find another B800. I use it with an Avatar 8ohm SB112 and a 4ohm B212, and any combination of these cabs with this amp will cover gigs of any size and type. From quiet restaurants with a singer, congas, and acoustic guitar, to medium sized stages playing sludgey metal with 2 guitarists and a loud drummer whose symbols I want to take away, I have never wanted more or less power from the head. The tone is representative of how the EQ is set and what bass and cabs you're using.
