Query: I wasn't impressed

This book does describe the logical patterns of the C-A-G-E-D sequence. Seeing how these patterns interconnect may be enlightening, but, it's not the revolutionary way of thinking the author would lead you to believe. One dissapointing thing is that the pentatonic scale is the basis for this book and when you try to adapt it to other scale forms it becomes less apparent and falls apart completely with some scale shapes. When the book eventually begins to discuss modes (which it tries hard to avoid in the first two sections) it glazes over them and doesn't convey any real information. It focuses on scale forms yet the actual underlying scale goes by a different name - confusing. You may find this book enlightening to a degree, but it won't revolutionize your playing or the way you look at the guitar. If you're looking for a good fretboard / music theory book for the guitar, this book will only get you so far.
