First, choose between a six string, a twelve string, and an electric guitar. Then choose the key you want to play in (the chords you want to play). And that's it! Now you can rock the party! To get that real guitar feel we included Easy Keys and Velocity Strumming. Easily switch between chords with the tap of a button. Strum or pick strings individually. Strum or tap in the center of the device for full volume, and at the edge of the device for quieter notes.
