There's a great interview and lesson with George in the new GuitarOne magazine where he lists some of the gear used on Furious George.
Here's the list...
1965 Marshall Plexi Super-100 & TNT 4x12 cabinet
ESP Tiger & signature series guitars all strung with Dean Markley strings with Seymour Duncan
Screamin' Demon pickups.
Dunlop Picks (light & flexible ones)
He also mentions his new amp from Peavey called the Brahma which is gonna be unveiled at the Jan 2005 NAMM show [img]images/smilies/woot.gif[/img]
