I agree with one poster who said Chet Atkins is the greatest guitar player ever. He is absolutely flawless and a complete master of his instrument.
Now, as to the greatest ROCK guitar player ever, I would have to say Eric Clapton. He has everything going for him: longevity, influence, plus he has proven he can play other styles besides just rock. And in my book, it is not enough just to be influential. Yes, Hendrix was influential, but that alone is not enough to make him the greatest. Top 20, yes. But he did not have the same mastery of his instrument as others before and since. There are several guitarists who I would say are much better players technically than Hendrix, including Stevie Ray, Eddie, Carlos, and Joe Walsh. No doubt they were all influenced by Jimi, but again, they are better technically, which I think elevates them above him.
In fact, in terms of influence I would argue that both Chuck Berry and Buddy Holly had as much or more influence than Jimi did, and had at least as much guitar skill as he did.
Now, if Jimi had LIVED and continued to improve skillwise I might be saying he was the greatest ever. But based on what he did in his short life, that qualifies him for top 20, but not #1.
