Heheh I know that is a real nice thick tone. Guess what?? I can tell you the secret to 75% of that earth-shattering tone!! ....
...Its called a STUDIO! Hehehe

No gear on this earth will give you a tone like that live. That tone was derived from many layering of different guitars with different eq's and all blended. You too can try to get this tone in the studio but the closet your gonna get is to use the same gear Carlos uses...which I think was pretty much your question...
He uses custom PRS 24's or 22's, not sure which. Dragon 7 pickups on all models. I believe his main amp rig consists of the usual (yawn) Triple Recs into Rect 4X12's... Tons of effects. Check out guitargeek.com
They have the whole low down i Believe....
