For Tom Morello's Solo on Guerilla Radio, He uses the GCB-95 toe down, so that its all trebly, and uses his killswitch "picking" technique, as he prefers to call it, while running his fingers on the E,A, and D Strings. I had this video where he explains this, but i cant seem to find it anymore.
I just listened to the White Stripes' Icky Thump, and it is one of the weirdest (amazingly weird) solo i have ever heard. I believe Jack White uses the Electro-Harmonix POG on this. (correct me if i'm wrong)
