This version of the ChordBuddy will work on necks no smaller than 1 1/2” and no larger than 1 7/8”. As soon as the ChordBuddy is properly attached to your acoustic or electric guitar, you will be able to make 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 ChordBuddy at all! Each package includes the ChordBuddy as well as instructions on how to properly attach the device to your guitar. The lesson plan and companion mobile/internet download will have you playing popular songs in no time. A ChordBuddy Songbook is included that contains either 60 or 100 songs, depending on the version that is packaged with the ChordBuddy and shows you how to play them with and without the ChordBuddy.
