Yeah, but it's stereo, right? Like the G-major OG?
I use it in a 2U rack with an Engl 530 preamp. I can change between the channels and the gain structures.
Combined with a Eurekaprom FCB1010, it's a versatile and good sounding rig.
The Axe-fx is probably better sounding, but it costs twice to thrice as much, at least over here. You can get an Ultra for 700$, and the G-major OG for 150$. Depends on what you want to spend, and how picky you are. I play rock and metal, and I've never been anything but satisfied. Then again, I'm not a "it can always sound a little better.." kinda guy. If it sounds good, it is good. Everything at noon, and let's play instead of tweak
