Dual isolation

Ojai’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, Ojai delivers clean, reliable power to all your pedals, on any stage anywhere you play in the world.

Never run out of outputs

Have a growing rig? Ojai is part of an expandable system. Gain more outputs by connecting additional Ojai units to the 24V Thru jack. Or use Ojai to add five more outputs to our Zuma power supply (sold separately).

Never run out of outputs

Is your pedalboard growing? Gain more outputs by connecting additional Ojai units to the 24V Thru jack. Or use Ojai to add five more outputs to our Zuma power supply (sold separately). Ojai is 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. Ojai 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, Ojai will deliver clean, reliable power to your pedals, even if the venue has dirty power.

Dual isolation

Ojai’s all analog circuitry offers two stages of isolation. Each of the five 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. Ojai 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: Ojai is green at heart. Significantly more efficient than linear power supplies, Ojai is able to deliver substantially more current while handling a much wider range of input voltages. Ojai’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 Ojai, 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 Ojai power supply unit goes through the same rigorous Audio Precision testing that our pedals go through. With Ojai, your pedals will sound the way they were designed to sound.
