Love Grissom. Huge 2nd for Saxon pub gig. Fantastic setting. I got to hear him in a tiny place in Houston maybe 3 years ago where he used amp, no mic in a little room. His amp in the room tone was just as good as it gets and his trio is killer. He had Glenn Fukunaga on bass that night and they were totally on fire. He always brings it though. Just a fabulous player. I remember hearing him with Storyville where he was using a Marshall stack and was so loud they pulled him from the PA. In front of him, it was magnificent and the other guitarist inaudible and away from him, he was hard to hear. He has solved that problem with his current rig and gets maximum tone without being blisteringly loud.
PS if Cliff wants to model his amp, I have both 30 and 50 watt versions. Great amps. As noted before, it’s his hands and concept that makes it happen. His guitar really helps, too. The DGT is very unlike most PRS guitars and has killer vintage sound.
