Big Joe Stompbox PB-101 Power Box Isolated Pedal Power Supply

Fully-Isolated To Protect Your Signal Path From Unwanted Noise

Written by

Elliot Stent

The Big Joe PB-101 Power Box is a fully-isolated pedal power supply that protects your signal path from unwanted noise and interference. Featuring eight noise-free, 9V power outputs; the Big Joe PB-101 is ideal for medium-sized pedalboard setups that feature a variety of stompboxes.

Six of the PB-101's outputs provide 100mA of current, while the other two offer 300mA for thirstier digital effects. Various switch combinations allow 12V and 18V output options too, which are ideal for niche vintage pedals that have unconventional power requirements. Two of the outputs also feature variable (VAR) voltage controls to simulate worn out batteries; a great feature for overdrive pedals!

An AC courtesy jack for pedals requiring AC only is provided in the back, and multi-colour LEDs for each of the eight outputs makes it easy to see the voltage selected for each output. PB-101 covers all of the bases and makes powering your pedalboard extremely simple!
