I've read a lot of conflicting reviews on this head (not the Mini Mo pre-amp, the head with an amp in it also). Seems to be no middle ground. Some LOVE it and others HATE it. I found these reviews on Harmony Central and Bass Gear Review and one here in the TB review section, but doing a search here in the Amps forum comes up with nothing (tried Mo', Mo and Mo`). So come on and chime in... Thanks!
