This is a minimal drone synthesizer capable of dense sounds. Two oscillators modulate each other while a third selectable LFO adds more interesting rhythmic drones. There is also a low pass filter and volume. A CV input allows you to power the device with control voltages from 0-5V for interesting automated power sag results.
The case is extremely tough die-cast aluminum painted black. The CV input is 1/8″, and the mono 1/4″ audio output makes it easy to connect to amps, effects or recording equipment. It is powered by an included 9-volt battery or 9V center-negative DC adapter. This was designed and hand-built in Oakland, California.
