Alexander Pedals Jubilee Silver Overdrive Roaring like a British Lion from Wembley to the Sunset Strip, the Jubilee is ready to melt faces. Sure, it can do subtle but that's no fun. Crank it up and rock out. The Jubilee requires a DC power supply with a 2.1mm pin, center negative. 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. Controls: Loudness: Controls the output level of the pedal. Drive: Adjusts the gain and distortion of the pedal. Treble / Middle / Bass: Passive three-band tone stack, voiced like a British amplifier.
