This is played by making contact with the two plates. Pitch is controlled by the resistance of the player?s skin. The stronger the touch, the less resistance and higher the pitch. The lighter the touch, the more resistance and lower the pitch.

Use the included alligator clip cable to experiment with attaching any conductive material to the contact plates. Metals, liquids, graphite pencil or other people work well.

There is also a filter and volume control. It has a mono 1/4? output and is powered by either an included 9V battery or 9V DC Center-Negative Power supply.
