I think it was the AxeFX II in the background. The level lights were going, and his cable was going in that direction. That said, what intrigues me is that he said the demo was for a new amp modeller software...
I kinda thought it sounded like an old Rockman X-100. Just being honest.
He's going through the Axe Fx, but likely as a recording interface.
The 12RackNew Eleven? Right?
