Product Description

Never worry about power again.

Zuma is the highest horsepower, most technologically advanced effects pedal power supply of its kind. Zuma offers nine high-current, individually isolated, ultra-low-noise outputs—each with its own dedicated regulator and custom transformer. Designed to meet the needs of today’s players, each output provides a staggering 500mA of current.

Zuma’s dual-stage topology, pre-regulated outputs, optically isolated feedback, and advanced multistage filtering result in a power supply that allows your pedals to achieve their highest possible dynamic range.

Never run out of outputs.

Have a growing rig? Zuma is part of an expandable system. Add more outputs by connecting a Strymon Ojai (sold separately) with the 24V Out jack. Use Zuma by itself if that’s all you need, or as part of a truly expandable, modular power distribution system that can grow with your pedalboard.

Hear your pedals, not your power.

Many popular guitar pedals were originally designed to work with batteries. Since batteries are inherently very low noise and not susceptible to ground loops, these pedals often were not designed to be resistant to noise from power supplies. Our ultra-low-noise design prevents power noise from bleeding into the audio signal, allowing your pedals to deliver the highest possible dynamic range.

World tour ready.

Playing gigs all around the world? No need to purchase separate power supplies for your international tour. Zuma has automatic worldwide power compatibility built-in (when connected with the appropriate IEC cable). Whether you’re on 120V, 240V, 100V, or any variation in between, Zuma will deliver clean, reliable power to your pedals, even if the venue has dirty power.

12V and 18V Options.

Do you have pedals that require 12V or 18V? Zuma has you covered. Two channels have selectable 9, 12, or 18V output voltages.

Some analog pedals designed for 9V operation may provide higher output and/or more clean headroom when run at higher voltages such as 12V or 18V. However, others will simply start smoking and melting, so please check with the manufacturer of your pedal before operating at a higher-than-standard voltage!

Dual isolation.

Zuma’s all analog circuitry offers two stages of isolation. Each of the nine output channels is individually isolated from the 24V DC, and the 24V DC is isolated from the AC input power, eliminating ground loop and AC line noise issues. Zuma also provides dual power regulation: Wide-bandwidth optically isolated feedback loops on each channel, as well as on the input, allow both the input and outputs to adjust for changes, ensuring solid output under changing load conditions.

Energy efficient.

Don’t let the blue chassis fool you: Zuma is green at heart. Significantly more efficient than linear power supplies, Zuma is able to deliver substantially more current while handling a much wider range of input voltages. Zuma’s high efficiency design delivers high-current power distribution in a compact unit, for a small carbon footprint and a small pedalboard footprint.

Design Team

Our power design team has over 25 years of experience in power system design, from developing mission-critical power systems for the aerospace industry, to developing best-in-class power supplies for top-selling power amplifiers, studio monitors, guitar amplifiers, and more. We’re using this vast experience to provide clean, dependable power to all of your effects pedals.

Breakthrough Technology

Strymon has solved the switching power supply problem. With our dual-stage topology, pre-regulated outputs, optically isolated feedback, and advanced multistage filtering, we have designed a switching power supply that is actually quieter than linear units.

Audio Testing

To make sure your pedalboard delivers the best sound quality possible when powered by Zuma, we did extensive listening tests with every pedal we could get our hands on, and we audio test each and every unit in our lab. In fact, every Zuma power supply unit goes through the same rigorous Audio Precision testing that our pedals go through. With Zuma, your pedals will sound the way they were designed to sound.

FAQ

Q: What are the dimensions and weight of Zuma?

A: Zuma dimensions: 6.8″ x 3.3″ x 1.8” (173mm x 84mm x 46mm)

Zuma weight: 1.25 lbs. (680g)

Q: How many Ojai units can be linked to Zuma?

You can link as many as 6 Ojai units to your Zuma, powering up to 39 effects pedals. While it’s unlikely that anyone would go to such extremes, we wanted to ensure Zuma delivers maximum flexibility and expandability. A much more likely scenario would be to link 1 or 2 Ojai units to your Zuma, powering a combination of up to 19 high and low current draw pedals.

Q: What Pedaltrain mounting options will be available for Zuma?

As Zuma is lightweight at 1.25 lbs, you can use Dual Lock® to mount underneath your pedalboards.

Strymon also offers the Zuma Mounting Kit, which consists of two aluminum brackets that can be used to mount Zuma underneath your Pedaltrain.
