High Horsepower, Low Profile.

Zuma R300 is the highest horsepower, most technologically advanced low profile effects pedal power supply. You get clean, rock-steady power for your 9V, 12V and 18V effects pedals in a pedalboard friendly, expandable package, giving you room to grow. Zuma R300’s ultra-low profile design means that it can fit under just about any pedalboard.

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.

Dual isolation - Zuma R300’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.

Ultra-low profile and noise - Zuma R300’s ultra-low profile design means that it can fit under just about any pedalboard. With built in threaded hardware, mounting to your board is simple. 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. The ultra-low-noise design prevents power noise from bleeding into the audio signal, allowing your pedals to deliver the highest possible dynamic range.

Never run out of outputs - Have a growing rig? Zuma R300 is part of an expandable system. Add more outputs by connecting a Strymon Ojai or Ojai R30 (sold separately) with the 24V Out jack.

Energy efficient - Don’t let the blue chassis fool you: Zuma R300 is green at heart. Significantly more efficient than linear power supplies, Zuma R300 is able to deliver substantially more current while handling a much wider range of input voltages. The high efficiency design delivers high-current power distribution in a compact unit, for a small carbon footprint and a small pedalboard footprint.
