This is the Quad Plague Bearer from Flight of Harmony. This is from the limited final run of units (#5/10) and ver 3.3 of the circuit. This was kept in a smoke free studio and looks and works perfectly. This is a custom unit of the run as there are 1/4" in and out jacks added to the unit to make interfacing with external hardware easier. The unit was built custom by Flight of Harmony. Comes with power supply. Can also be powered by two 9-volt batteries.
