Gemini 2 is the way to go!
While I did not buy my Gemini 2 from Sweetwater, I would have had they been in stock when I was ready to buy. I have tried using my Axe FX II through every combination there is. Whether it was my QSC K12's, two Mesa 1x12 cabs with a power amp, or a tube power amp with a 4x12 cab, the Gemini 2 is the best combination I have tried yet. Plenty of power, true FRFR, amazing construction, and the 'look' of a guitar amp. Active wedges were good, but the molded plastic had too much influence on the tone. The Baltic birch construction of the Gemini 2 just lends itself to a more balanced tone, the 'amp in the room' feel. It just seems to resonate better to me. Tons of headroom, you can play clean tones through this product at very high volume with no breakup. That's a must for me. It has all the bass and treble response as anything I have tried, but the treble is so much smoother and the bass is full, yet not overly boomy which can kill guitar tone. I hate making this comment as I don't want to offend anyone, but I also like my backline to look like a guitar amp and not a PA speaker. With careful placement, the Gemini 2 can be mic'd up just like a traditional cab as well. I'm very pleased and feel like this is the best overall solution for me, glad I chose the Gemini 2 and I think you would be too.
