I was wondering what amps he was using as well. After zooming in on some hi res photos from last night, I'm pretty sure they are Fat Jimmy amps.http://fatjimmyamps.com/
There are only three adjustment knobs visible on the amp on the left and a single toggle on the right by the power light. The amp on the right has two adjustment knobs and a toggle (on the left side) and two toggles on the right side.
I liked his tone last night. Curious if anyone has any more details on the actual specs and cab/speaker config.
