This book/audio pack by award-winning guitarist and distinguished teacher Jack Grassel will help rhythm guitarists better understand: chord symbols and voicings; comping styles and patterns; equipment, accessories and set-up; the fingerboard; chord theory; and much more. The accompanying audio includes 74 full-band tracks.

Audio is accessed online using the unique code inside the book and can be streamed or downloaded. The audio files include PLAYBACK+, a multi-functional audio player that allows you to slow down audio without changing pitch, set loop points, change keys, and pan left or right.
