The Guitar Toolbox series is a ground-breaking new method of learning modern guitar based upon moveable scale and chord shapes.

Cal Williams Jr.: Introduction To The Guitar Toolbox - Part 1 steers away from the traditional classical guitar methods used in other guitar books and is the first book of its kind to approach the guitar from a modern guitarist's point of view.

The Guitar Toolbox series takes the student from the simple pentatonic scale foundation to playing the complete major, minor and blues fretboards.

Cal Williams Jr.: Introduction To The Guitar Toolbox - Part 1 also infuses the students chord palette with triad chords based around the 1, 4, 5 and the complete perfect chords in all keys.
