It's a great book if you've only bought issues of Acoustic Guitar Magazine here and there throughout the last couple years. But if you've been a long-time subscriber like me you'll notice that this book is another in the latest series of String Letter publications that are basically reprints of Acoustic Guitar magazine articles. Granted, there is the addition of some new information and exposition, largely in the form of introductions to each chapter. Still...I bought this book and I'm thinking "hey, I bought most of this already!".
