Strymon ZUMA 300 Effects Pedal Power Supply
High power, low profile.
The Zuma R300 is the most powerful and technologically advanced power supply for effects pedals. You get clean and stable power for your 9V, 12V, and 18V effects pedals in an expandable, pedalboard-friendly enclosure, allowing you to grow. The ultra-low profile design of the Zuma R300 means it can slip under any pedalboard.
The two-stage topology, pre-regulated outputs, optically isolated feedback, and advanced multi-stage filtering provide a power supply that allows your pedals to reach their highest possible dynamic range.
Double isolation.
The fully analog circuit of the Zuma R300 offers two levels of isolation, completely eliminating ground loop and AC line noise issues, allowing your pedals to sound as they were designed.
Ultra-low profile.
The ultra-low profile design of the Zuma R300 means it can slip under any pedalboard. With built-in threaded hardware, mounting on your board is simple.
Never run out of outputs.
Do you have an expanding setup? The Zuma R300 is part of an expandable system. Add additional outputs by connecting a Strymon Ojai or Ojai R30 (sold separately) with the 24V Out jack.
Design team
Our power supply design team has over 25 years of experience designing power systems, from developing critical power systems for the aerospace industry to crafting top-tier power supplies for power amplifiers, studio monitors, guitar amplifiers, and more. We use this extensive experience to provide clean and reliable power to all your effects pedals.
Revolutionary technology
Strymon has solved the problem of switching power supplies. With our two-stage topology, pre-regulated outputs, optically isolated feedback, and advanced multi-stage filtering, we have designed a switching power supply that is truly quieter than linear units.
Audio testing
To ensure your pedalboard delivers the best possible sound quality when powered by the Zuma R300, we conducted extensive listening tests with every pedal we could get our hands on. In fact, every Strymon power supply undergoes the same rigorous Audio Precision tests as our pedals. With the Zuma R300, your pedals will sound as they were designed to sound.
