This is a lo-fi synthesizer that is played by bridging a connection between the two contact points. The pitch is controlled by the amount of resistance. The more resistance or lighter touch produces lower frequencies. This oscillator is then modulated by a LFO, giving this device very nice throaty, almost vocal sounds. It can also be played through multiple people creating a human chain.
The two knobs control the speed of the LFO and volume. It is powered by a 9volt battery. A red LED indicator flashes in sync with the modulation. Audio out via 1/4″ jack. The case is a tough die-cast aluminum painted gray.
