This is a great program for intermediate to advanced players. Desi knocks it out of the park with his easy to follow lessons!

Desi is a great teacher and this course has greatly assisted me to both understand and move my guitar playing to the next level. I purchased this course and his Guitar Theory for Dummies course.

What I appreciated about Desi's approach is the way that he combines the practical instruction on playing the guitar and the music theory that goes with it so you understand why you are doing what you are doing. I have been playing for years but have progressed more over the last year, using Desi's material, than I have in all of my previous years of playing.

Very well written and easy to understand. Desi also offers a free podcast that follows along with each chapter. Highly recommended for guitarists of all ages and skill level.

This system and clear approach to guitar theory helped me improve my playing ten-fold within a week. What I had struggled with for years due to unclear teaching techniques was revealed quickly within these pages. Thank you for the freedom to play!
