The Zuma R300 stands as the most powerful and technologically sophisticated low-profile effects pedal power supply available, engineered to provide pristine power delivery for your entire pedalboard setup. This remarkable unit supplies clean, rock-steady power to your 9V, 12V and 18V effects pedals whilst maintaining an ultra-low profile design that fits beneath virtually any pedalboard configuration.
Advanced engineering sets the Zuma R300 apart through its dual-stage topology, pre-regulated outputs, optically isolated feedback, and sophisticated multi-stage filtering system. These technical innovations work together to maximise your pedals’ dynamic range potential, ensuring each effect performs exactly as the manufacturer intended.
The all-analogue circuitry incorporates two stages of isolation, completely eliminating troublesome ground loop and AC line noise issues that can plague pedalboard setups. Built-in threaded hardware makes mounting to your board straightforward, whilst the expandable system design allows you to add more outputs by connecting a Strymon Ojai or Ojai R30 (sold separately) via the 24V Out jack, making it perfect for growing rigs.
