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.

Never worry about power again.

Strymon Zuma is the quietest and most powerful pedal power supply of its kind, capable of powering a huge number of guitar pedals silently and reliably with a staggering 500mA of current available at each output. With nine high-current, individually isolated, ultra-low-noise outputs – each with its own dedicated regulator and custom transformer – Zuma is the most advanced isolated pedal power supply available today.

A pedalboard can be a noisy place, and your choice of power supply can have a huge effect on the noise level and transparency of your guitar tone. We designed Zuma to address the main pain points guitarists face with dual-stage topology, pre-regulated outputs, optically isolated feedback and advanced multi-stage filtering – so you can rest easy at the gig, knowing that your pedals and rig will sound the absolute best that it can.

Dual isolation.

Zuma’s all analog circuitry offers two stages of isolation, completely eliminating ground loop and AC line noise issues, allowing your pedals to sound like they were designed to sound.

World tour ready.

With automatic international power compatibility built-in, Zuma delivers an abundance of clean, rock-steady power to all your pedals, on any stage anywhere you play in the world.

Never run out of outputs.

Have a growing rig? Zuma is part of an expandable system. Add more outputs by connecting a Strymon Ojai or Ojai R30 (sold separately) with the 24V Out jack.
