A number of years back I went down to Nashville (from Minneapolis) and hung out with Dann Huff in the studios, for two sessions. He had a mountain of gear at each session. His main guitar was the Tyler moded Strat, but he also had a Les Paul and Tele, and PRS axes.
His amp heads were Peavey Classic 50, a Fender head, and a Matchless. He had two fridge sized racks with preamps in one, and effects in the other, all controlled by a Bradshaw system.
I didn't ask him what he used on the Giant sessions, but he showed me at his house the room where he cut the demo's for Giant.
Dann was very gracious to allow me in to his world. He's an AMAZING guitar player, and a very nice guy. His sessions were mostly one-take, but at an Elton John session ("Duets" CD) he was run thru the ringer by Producer Barry Becket. However, Dann got it done beautifully!
Nowadays Dann is an extremely busy in-demand Producer. Good for him! He's doing a GREAT job on all his projects. His work with Keith Urban has really helped Keith get off to a big career. Way to go, Dann!
