It also depends largely on which era we're talking about... I mean, "Are You Experienced" is very different from, say, "Band of Gypsys."
Hendrix is more aboutt he vibe than the tone for me, anyway... I mean, a strat driving an amp set for a thick, fat, fairly dark lead sound will get you close enough, and the rest comes from his sick (in the new england slang sense, meaning "really cool") sense of groove. He's just so laid back and loose while never sounding sloppy... It's got this over-the-top sense of, idunno, badassness to it. Anyone who's ever heard the "Hendrix: Blues" CD knows exactly what I'm talkign about. That disc is why Jimi's my favorite blues guitarist. Unreal.
