The book itself will tell you this information, and its clearly in the title-this is all about technique, theory gets the boot.If thats what your looking for then from what Ive already got out of this book I can say you will enjoy this.
The early chapters will tread some familiar ground if you know some scales and basic finger strengthening exercises.But even early on t has some interesting ideas that might make you improve your dexterity so dont skip by them. The chapter on sweep picking is one Im currently working on and has some ways of picking that seem unlike what others would teach, and work very well for making you think in a different way.
Theres also chapters on linear scale movement, chicken picken,alternate picking arpeggios, tapping,bending and legato.Thats a great variety, and if I had been at a slightly lower level of playing, would have found this to be an even greater deal.I plan on going through the whole book regardless, it simply cant hurt.Right now Im just filling in the gaps of my technique.
Problems I encounter with this book include the cd and how its tracks are arranged.There are too many exercises per track- there are hundreds of exercises crammed into 18 tracks.If you are jumping back into the book and happen to be in the middle of a chapter, its a bit annoying to scan by ten or more tracks to get to what you need. Some of the exercises arent organized well either.One pattern is sometimes broken down into three different sections, which are the same pattern just repeated on tab for one or more bars.It seems like a waste of space when it could have simply said"now, repeat this bar".But thats just me nitpicking.
If any of the above mentioned skills are something you need help in,get the book.For the price you can grab it easily, and as long as you go at a good pace I cant see you not improving.
