Here's my top 10
1. Trey Anastasio - Just love his style. No one else sounds like him. Listening to his solos just fills me with extreme guitar bliss.
2. Steve Hackett - Definitely the most versatile guitarist I've ever heard. Innovator of finger tapping. And don't judge him only by the stuff he did in Genesis. His solo albums show his true skill and versatility.
3. Steve Howe - Almost tied with Hackett because he is almost as versatile. And I do think he composes better guitar solos than Hackett. He also has a very original and distinctive sound, like Anastasio.
4. Jan Akkerman - This guy's playing is just sick. He really shreds **** up. Listen to any live version of Focus's Hocus Pocus on Youtube. It's never the same, but always awesome.
5. David Gilmour - Kind of the opposite of Jan. His playing is slower and simpler, but with more feeling than I've heard in any other guitarist.
6. Jimi Hendrix - Wasn't sure whether to include him, as his guitar playing technique never really impressed me as much as his showmanship with the guitar. Pete Townshend also deserves a mention for this, but didn't feel it necessary to include him on the list.
7. Duane Allman - Included him mainly for his slide guitar skill, but also for the way he and Dickey Betts harmonized their solos. In fact, I would have included Betts as well simply for Jessica and Ramblin' Man, but felt it would have been redundant.
8. Frank Zappa - Again, like Hendrix, this is more for showmanship than technique, but I really dig his playing on Apostrophe. I almost didn't add him until I realised how much I tried to play like him sometimes.
9. Robert Fripp - I never used to like his style, but couldn't deny his talent. But as I improved my guitar playing, I found myself drawing more influence from him than I thought, more in his approach towards guitar playing rather than his actual technique.
10. Maury Muelheisen - I had to include this underrated classical guitarist who helped make Jim Croce's folk rock songs sound so good. Many of the first songs I learned on acoustic guitar were Croce songs, and it was hearing his guitar parts that made me want to learn it.
