KSE have used so many different amps live and in the studio. Guess what, they always manage to get pretty much the same sound of them all... Rectifier, Splawn Nitro, Triamp MKII, Framus Cobra, Framus Dragon, Soldano SLO100, Diezel VH4, and probably a lot more. No matter what amp they use, they still sound the same. You could probably go with any modern-voiced, high gain amp and as long as you're tuned down a step and using an EMG 85 in the bridge of your guitar, you'll get pretty much the same sound.
I've recorded a video in the past with my Jackson, tuned down, with EMG 85 and, while it was recorded with my computer's built-in camera, it doesn't sound all that bad. I'm not the best player out there, but you'll get the idea I guess...
