Youtube is a wonderful tool for musicians. I recently started learning some guitar solos shown on youtube.
One artist whose playing I admire very much is Jeff Loomis (Nevermore and solo artist).
In this post (http://www.youtube.com/watch?v=WDs9EKJtpTs) he uses a classical basis with some delay to create a stunning little piece. I spent 3 afternoons transcribing this using tuxguitar, then export to ascii so I could add the fingering.
