Free Power Supply Info: 9V 500mA AC Adapter

A wall outlet transformer with very specific type of plug / power / voltage / polarity is needed and we include one for free so you will not need to waste batteries. It is lightweight, cool to the touch (efficient), and narrow (1”) so it should only take up one slot in your power strip. Produces quieter operation of NS-2 than some other AC plugs.

It produces 500 mA of current to easily power multiple pedals. The NS-2 only “sips” 20mA of current but the NS-2 includes a power output port so this power supply can be shared with 7 other compatible sections of your pedalboard via optional Boss PCS-20A wiring (which is a power “sharer” & not a power supply). 9V Battery (also included, accessed by unscrewing knob on pedal).
