Hi Ivan, I only got in 2 gigs with the BB2 before the 1st lockdown so not much experience yet. I used the BB2+SM and compared to the SC+SM the sound was bigger in every direction. Lower, fuller, fatter, higher, but it's a bigger cab, so I guess that's to be expected. The B string was thunderous. I wouldn't use this rig for every band, the SC+SM has just the right flavour of "vintage" for me. I've used the SC+SM for a couple of years and didn't have a sensible reason to buy the BB2!! If I had to go back to 2 cabs I'd choose the SC+SM. they just sound so good together.
