Paul Gilbert
Paul Gilbert is one of the most technically proficient rock guitarists today. He's played in bands Mr. Big and Racer X. He graduated from G.I.T. in 1985 right after forming Racer X with other students from the school. He currently has a monthly column in the European guitar magazine Total Guitar.
I love reading Paul Gilbert's column in Total Guitar. It's really improved my playing.

Paul Gilbert owns anyone you put in front of him on guitar. End of discussion.
