A paperboard bottom wall completes the sound box, and pegs are inserted through the apertures in the pegboard. Strings extend between the pegs and the bridge, and a continuous ridge on the upper surface of the sound box receives a paperboard insert therewithin. Apertures are formed in the sound box, and simulated manual control buttons are located on the upper surface of the sound box.
