nope.
he didn't change music he just contributed his talen, i'm sure he would be insulted to be called more influential then Hendrix just becasue he knows how influential hendrix was.
Jimi Hendrix, now theirs a guy who could be named the most influential guitar player.
Listen to the Monterray Pop Festival from 1967. Just listen to the whole thing and you'll notice that Jimi Hendrix (this is his first time in America after gettin good) is playing music completely different then anyone else, then listen to other popular bands throughout the ages untill now and you'll see that he completely popularized his style.
But i'd call Buddy Guy the most influential for influencing Jimmy (as he was known before he was popular) to play and then Eric Clapton for influening him to try and invent new ways to play the guitar and twist blues into what Jimi eventually made his version of the blues, Hard Psychedelic Blues (Purple Haze).
But by far Jimi Hendrix made the largest mark on popular guitar music simply becasue he didn't just influence a few people into making new kinds of music, he is known by everyone to have revolutionize how the electric guitar is played.
