I'd say right now, I could use either of my cabs with the CB's or the BB's and be happy. If I were tasked with playing more modern stuff, I'd probably stick with the Creamback cab, and use the BB for more classic rock type stuff but I feel like they could interchange pretty easily with some EQ tweaking. I had a little fun with them last weekend, and opened the amps up a bit... First time I've walked away with a noticable ringing in my ears in a long time. LOL I'm thinking about investing in a decent wireless guitar rig, so I can stay out in the separated part of the basement.
When I got done, and went upstairs.. All my wife said was.. "Wow, you were really jamming down there!". LOL
