The Greatest Guitarist of All Time.

[KDinsmore]

John McLaughlin. I've seen him in every iteration except playing for Miles. Technically without peer when younger (not to take away now). 

Jeff Beck. Always improving and looking for something better.Technical, tone, sound the best.

Robert Fripp. Without peer in composition and playing ability.

Lots of shredders abound. YouTube will teach you how to get it done these days with lots of practice. Just visit a Guitar Center and you'll see kids playing incredible riffs.

This is the deal: Lots of players but hardly ANYONE can write. That is why everyone is in love with all the older players. And that is where you divide the great from the Karaoke's.
