They use axe's now. Monument was with engl powerballs, carving desert canyons was mesa for the most part, probably mark iv's. Chris uses Sherman guitars now, and a newer Artinger, Travis uses a JP7 and he had some sort of custom Tele shaped guitar that he used for CDC. They have a pretty basic lead tone, boosted mids with a smooth q.
Any nicely dialed in high gain valve or high end axefx with delay should get you there really, the rest is pretty much in the fingers.
