Strymon Zuma R300 Low Profile Pedal Power Supply

Strymon Zuma R300 Pedal Power Supply

The Strymon Zuma R300 is a low profile, high-current pedal power supply designed to deliver clean, reliable power for modern effects pedals. Its compact design fits beneath most pedalboards while providing fully isolated outputs to minimise unwanted noise and maximise pedal performance.

Featuring dual-stage topology, pre-regulated outputs, optically isolated feedback and advanced multistage filtering, the Zuma R300 supplies stable power for 9V, 12V and 18V pedals. It can also serve as the foundation of a larger Strymon power distribution system by linking compatible Ojai expansion units as your pedalboard grows.
