Correct me if I'm wrong, but the rig set up in the video was the Friedman guitar with Motor City pickups into the Friedman Cantrell amp, slaved out to a Roland SDE-3000 delay feeding a Matrix power amp in the rack with 250mS delay to one 4x12 cab and 500mS to a second set of 4x12 cabs. The 4x12's had V30's in the bottom and Greenbacks on the top with overall impedence of 16 ohms each.
