Has there been any comparison between this and the Genz-Benz Shuttle 12.0? They seem similar as they are both hybrid heads that go down to 2 ohms, which is what I'm primarily interested in (a "big" head compared to my GK MB2-500 that will go down to 2 ohms and is either tube or hybrid).
Technically The 12.0 doesn't do 2 ohms, it does two loads of 4 ohms each. So if you had two four ohm cabs, either would work. Truthfully, the Mesa is in a different class from the micro heads though (I've owned the GK, the Shuttle 6 and the LMK) as far as headroom goes. And while in theory the 12.0 could do more damage than the Carbine through 2 4 ohm cabs, I kind of doubt it.
Plus the more traditional power amp of the Mesa just makes for a different quality to the sound than the micro heads. You really need to play one to understand.
