Not in any order.
Joe Satriani - I'm a huge fan of his style and his constant deliverance of solo's album after frickin album. With Surfing With the Alien still and always being my favourite of them all. A great guitarist.
Jimi Hendrix - The god of all that is guitar. Truely worthy of that name and will always be a legend. This guys guitaring has always been awesome to me and will remain even when he raises back from the dead and wails his guitar to the masses once more. [oh, he will!!]
Jeff Loomis - The lead guitar for Nevermore, this guy can spew out solo after ****ing solo and make them all sound as awesome as the first, and better! combined with the rest of the band, it puts a new meaning to word awesome.
Micheal Angelo Batio - The greats guitarist when it comes to fast playing, becuase this guy makes it sound so awesome! Watch any of his vidoes where he's showing off, you'll soon sink down to your place in the guitaring world. Becuase this guy knows what he's doing.
