As soon as the Chord Buddy is properly attached to your acoustic or electric guitar, you will be making music! Within a few weeks, you’ll begin removing some of the tabs and making the chords on your own. In two months, you’ll be able to play the guitar with no Chord Buddy at all. ChordBuddy works on full size steel string, and electric guitars. The Chordbuddy makes the chords G,C,D,Em in the Key of G. This listing is for the ChordBuddy unit only and does not include any books, DVD's or any other literature
