The Mini Iso-Brick delivers quiet, noise-free power to your stompboxes without eating up a ton of pedalboard real estate. Five fully isolated outputs, including a 9/18-volt switchable output, accommodate a wide range of pedals while eliminating annoying ground loop noise. Expansion is as easy as inserting a splitter cable. Troubleshooting is also a breeze, thanks to super-bright LED status indicators. Beyond that, this road-ready power supply is built like a tank.
