The Jubilee requires a DC power supply with a 2.1mm pin, center negative. The Jubilee will operate on power supply voltages up to 18V and does not use a battery. The Jubilee should work fine on a multi-pedal "daisy chain" connector, but if you encounter excessive noise or hum try a separate power supply.
