His amp set up was one Dumble, one Two-Rock, one Marshall, and one Marshall clone of some sort. One of the roadies said he was only going through two amps with the other two as back-ups. I don't know if that was true but his tone was absolutely monstrous. His Les Pauls sounded like... well, Les Pauls. In other words, unlike many people who perform at that dB level, you could clearly hear the difference in guitars. The Pauls were really fat -as in lots of midrange that he didn't try to dial out. The strat was very stringy (stupid adjectives, I guess we have no other way to communicate) and "twangy." I saw him in a small theater and I didn't require ear plugs: he used plexiglass shields in front of some kind of huge 4-12 cabs. That was nice because his band f^&*in' smoked as well. After seeing the scope and breadth of his playing (blues...to...everything else in one performance), I feel like quitting guitar! One thing I have to say; his tone was not all that unlike Eric Johnson's tone (a tone I never cared for all that much). However, it was like watching someone with Eric Johnson's control and virtuosity with much more gut, earthiness, and sense of humor.
