I've owned this book for years, and I've also been playing guitar for years, and I've found one really does go with the other. I would class myself as an average guitarist, but beyond what most teachers can teach. As such this book has been absolutely invaluable to assist in those "how the hell do they do that?" moments. If you've already got some playing experience, this book is useful on so many levels, if you're a beginner, it's a good place to start. I've been dipping in and out of the various sections of the book as my playing and experience has developed over the years, and the information is always there, from the different types and styles of guitar, to prominent guitarists of the ages, to setting up and construction of the guitar, pickup wiring diagrams, chords in every key, stage craft, using PA and recording equipment and guitar synths, what more can a book deliver? Spend your money, this book would be good value at ten times the price!!!
