Effects Pedal Power Supplies

Never worry about power again.

When we set out to design a line of effects pedal power supplies, we had one overarching goal in mind: to make sure you never have to worry about power again. 

ZumaZuma R300Ojai R30, and Ojai are the highest horsepower, most technologically advanced effects pedal power supplies of their kind.

Hear your pedals, not your power.

Dual-stage topology, pre-regulated outputs, optically isolated feedback, and advanced multistage filtering ensure your pedals will achieve their highest possible dynamic range while being as noise-free as possible.

Each individually isolated, ultra-low-noise output provides a staggering 500mA of current, meaning the days of not having enough current for those high powered pedals are over.

How the Strymon System Works

Zumas are self-contained units that plug directly into an outlet using a standard IEC connection. The Ojai side of the family needs 24V of power, which it gets from a Strymon PS-124 adapter, or from connecting to a Zuma’s 24V accessory output. 

This allows you to power additional Ojais from a Zuma, giving you additional isolated outputs for growing boards.
