That technique is an old blues technique and has been done many many time by various guitarists. I love Hendrix, I think what should be noted isn't the technique - that's just extreme proficiency - the likes of which I have seen even superior. No it's his soul in the playing that really defines Jimi.

That technique is even being utilized today. Not at all trying to be contrarian - honestly cause again I take your opinion over pretty much the rest on here lol.

However that's not fair to many guitarists.

But jimi was the man.
