This is my second take on this type of device. It is played by bridging the connection between the two plates. The more contact made the higher the pitch. You can experiment with friends by making a human chain of resistance.

With a very minimal design this synth is carved into a single piece of salvaged wood with an aged looking stain. Aside from the two contact plates you have a power switch/indicator light and 1/4″ audio output.

It is powered by an internal 9v battery under the left plate.

One of these is now in the very skillful hands of Jason Mullinax of Pilesar.
