I gotta think if you were/are basically happy with the Shuttle that the new 350 - especially with a 2nd BA10-2 would be a killer mini stack. As I have no need for drive, and like my Shuttle, I may have talked myself back into a 350 combo. If I think I need more I'd add another cab for the mini stack.
Yep. The drive is cool, but I've got drive pedals. Don't need a full 800 watts. The 2.67 ohms will power three 8-ohm cabs. As much volume as I will ever need.
