A guitarist worse nightmare.
I'm very happy with my one B-2.
For giggles I compared to the Markbass 2x10 (not sure of the model)
No comparison at all in the lowend.
You used have to be used to the lack of coloration that you recieve with the Acme.
For Markbass users I turn up the Mid Atten almost all the way up on the Acme and the VPF to about 11 on the MKII.
(Normally I keep the VPF off or just about)
From what I understand, the MB210 is not a good thing at all... probably as far away from the Acme as you can get. You might want to try the same thing with a Bergantino or Epifani210, or an EA NL-210... you might be quite surprised at the amount of usable low end that you can actually deliver to the audience without the need for hi pass filters etc., and how loud and full these can get with a very moderate amount of power.
The MB cabs seem to have very little in common with the amazing heads this company makes.
IMO.
