The ChordBuddy Guitar Learning System is designed to help you learn to make chords as you learn to play guitar. The ChordBuddy attaches to the neck of electric or acoustic guitars and guides you through learning basic chord fingering positions. It works in the key of G and makes the G, C, D, and Em chords. The included instruction book, songbook, DVD, and two-month lesson plan guides you until you learn to make the chords on your own and you’re ready to remove the “training wheels”. The ChordBuddy Guitar Learning System is $59.99 at Sharper Image.
