I think he has some mind boggling astonishing licks and riffs and a fantastic tone. He has a handful of spectacular songs. But as far as sitting down listening to him for hours on end, no not really. as far as not improving on Hendrix songs, I don’t know about that. There’s a live version of Voodoo Chile that in my opinion blows the doors off any version I ever heard Hendrix play. Also (again, my opinion) he had a MUCH better singing voice than Hendrix. Despite the god-like status we give Hendrix, I think most people would have to honestly admit that he was not a great singer. And back to the live version I spoke of, that’s really what SRV was...a spectacular live performer who recorded albums as a means to supporting his live show. As good as his recordings were, the live performances are really what wowed people. As far as the original question, I know several non-guitar people who are SRV fans, though I doubt they hold him in quite as high regard as guitarists.
