I have read countless testimonials about guitar books that guarantee results I never was able to achieve. This book actually delivered for me, and it has done so in a big way. My ambition, which previously eluded me entirely, has been to become fluent on the fretboard--to be able to improvise, follow changes, structure complex chords on the fly and the like. I tried so long in vain I decided I must just lack the necessary ability.
This book changed all that for me. I am doing things now I only dreamed of before. I don't know how the author figured it out, but he has come up with a way to communicate an understanding of music and the fretboard to both your head and, probably more important, your hands. Simple things like combining diagram exercises and playing, reinforced by having you speak the information out loud, really work to imprint the material on your fingers. The book walks you one step at a time, fairly painlessly, from simple to very complex. This thing is a gold mine. No kidding.
