The B28 was the game changer for me.
I really liked the MAS109 but when I gigged it alone I missed the *something extra* that the Flex Top provided. So I usually wound up bringing both, which defeated the goodness of the MAS109 as a standalone cab. Great cab, but the standard of comparison was another MAS cab
The B28 brings that *something extra*. In a wee little package. With more volume and more lows. GAS inducing indeed!
As previously mentioned, in the right room, the MA109 was the best upright cab I've ever tried in 30 years. Slab was good also. The main reason for the B28 is more headroom and that amazing up high mid-section. I backed a fairly loud 5 piece blues band with the 109 no problem, and had to push it right next to the limit a few times. Pretty sure the B28 will solve the headroom deal. Planning to get it up off the ground/stage for sure! Which folding folding stepstool do you prefer? I seem to not have luck finding one...
