My brother swears by this book:

Amazon.com: Fretboard Logic SE: The Reasoning Behind the Guitar's Unique Tuning + Chords Scales and Arpeggios Complete (The Fretboard Logic Guitar Method Parts I and II) (Fretboard Logic Guitar Method Ser): Books: Bill Edwards

And I've definitely noticed an improvement in his playing since he started getting into it.
afghooey Reviewed by afghooey on . First Act This is my first act with the electric guitar. It's a mesmerizing instrument, one that I hope to master in this lifetime. I have the drive but am lacking information. Terms like "appregios," "measures" strike no chords. Forgive the little pun there. Is there a book for dummies? Of course there is! I'm broke though. Any informative websites, one you trust and have learned from in the past, one that'll fill my head with guitar knowledge and not leave me lost in guitar jargon--Guitar players Rating: 5
