I strongly advise against this book. For me as a mediocre guitarist it's inappropriate. One should have the perfect technology to possess it with this book take the latter is touched upon here at any point. Instead, many guitarists and examples are given that you should listen times ... The sound samples on the CD act cobbled together carelessly and sound partly also played very dirty. I would guess that almost a trained guitarist with this book would be no better, but rather messy, he would build one on one in this book.
