What we say:

At A Glance:

A slightly scaled down version of the original Strymon Zuma, the R300 has 5 outputs (1 at the end is 9v and 1 9v, 12v or 18v adjustable) and pumps out enough ampage to power even the thirstiest of digital pedals and it’s super low profile and shrunken size means it fits under most pedal boards discreetly!

Features We Love:

Double Isolated Power

With the Strymon’s unique dual isolation stages you can rest assured your guitar sound will be free from pesky grounding and hum issues that are common with a lesser power supply and let the world hear how your pedals are supposed to sound!


As with all pedalboards, they all eventually bloom into a greater size! If you've become accustomed to the super clean hassle free vibe of the Zuma but have acquired more than 9 pedals, simply buy and attach a Strymon Ojai or R30 for extra outputs!

Super slim profile

The Zuma R300 has been on a diet and slimmed down to the perfect size to fit under most boards, even a smaller one! Simply pick up some Strymon mounting brackets or heavy duty velcro and get it stuck on the bottom!


  • Unique double isolation keeps the signal free from noise.
  • Expand with optional extras for more power outputs if needed.
  • Rugged and rock solid construction with new slimmer profile.
