Man so much to agree with in this thread; I'll just start rambling and hopefully I'll address everything.
1) Little Wing from Hendrix in the West - Few folks have mentioned this, that is one of the best versions of that song I've ever heard. Nice to see others feel the same.
2) Have to agree with the pre/post Hendrix age sentiments. His influence was clearly heard across the board when he debuted. From the Beatles to Clapton to Townsend folks changed the way they thought about music after hearing Hendrix.
3) Hendrix really used the Wah in a way few else have; as folks have mentioned he used it as a EQ when he wasn't going for a "wah" effect, and would set it flat to adjust his overall sound. Additionally he really did a lot of super subtle stuff with it that, honestly, I've heard few others actually perform properly. I started on guitar, and spent weeks as a teenager in front of an amp trying to work that stuff out; it's pretty intense.
4) I also wish he would have lived longer. That being said I've had a long standing theory that he was about to invent disco (listen to Dolly Dagger, for an example of this.) Really wonder how his legacy would look, had he lived, and that happened.....
