Yeah, and it's perfect. I have two of 'em actually. I keep one at home and one to go. I have an MB212ii at home, and aux in for practice, if needed, or use headphones, and have an MBP112 and 212 for rehearsals, shows, etc.
The modular nature of Plex + MBP cabs is perfect.
It's the sound I dig too, and I love it, but honestly I just get curious about other amps, and wanna get Genzy or Mesafied sometimes without going all in on one of their heads.
Also, I haven't had a passive cab since going MBP. You can probably answer this - whats the passive gk equivalent of the mb combo cabs?
