Requires optional power jack in order to use any power supply. Power jack is optional because it works and sounds best with a battery. If you get the power jack option then we can also sell you a nice quiet power supply for it. No reverse polarity issues on the power jack, normal 9V boss type will work.

 

The optional on/off volume pot allows disconnecting the battery by turning the volume all the way down. Then you can leave the pedal in your pedalboard without having to worry about unplugging the input cable to keep the battery from draining.
