I've got two MB200's now. I replaced my Shuttle 6.0 with one for my church rig, which is largely acoustic. It goes into a homebrew 1x10 with a BP102-4 in the low end crossed over at 700 Hz to a fabric dome tweeter. The rig actually puts out too much low end. I've got the MB200's bass knob turned all the way down.
I'm heartened to see some of you using the MB200 into a pair of SVT210AV cabs and making a night of it. I'm thinking of going that way. I was thinking that I needed to buy an MB800 for that fateful day that I get a secular gig. I still might. The idea of using an MB800 into a Thunderchild and calling it done is appealing.
I'm very happy with the MB200's though. Sweet little amps.
