Written by

Cian Hodge

Undoubtedly one of the most reliable PSUs you could incorporate into your guitar pedal setup. The Strymon Ojai R30 is a versatile, future-proofed expansion kit from one of the most technologically advanced pedal manufacturers in the business. Requires existing Strymon power system.

Future Proof Expansion

As your pedalboard grows, your PSU needs to keep up. The Ojai expansion kit contains a 24V thru jack and all necessary cables to expand on your original setup. Integration is simple. The R30 can be mounted under most pedalboards thanks to its low profile design.

Premium Variable Power

Run up to five guitar pedals on pure, isolated power eliminating ground loop and AC line hum. The Ojai uses premium analogue circuitry and components, ensuring reliable power wherever you are in the world - regardless of 120V, 240V, 100V or other voltage variations. Do your pedals require 9V, 12V or 18V? Strymon also have that covered with two switchable sockets.
