The Strymon Ojai R30 powers your most power-hungry pedals. Add this Ojai R30 Expansion Kit, and you double that pedalboard power. Each of the Ojai R30 Expansion Kit's five outputs pumps out a respectable 500mA for your power-hungry digital units. And its two adjustable outputs — 9, 12, and 18 volts — are ready for anything. And also like the R30, each output is fully isolated, with no ground and AC line noise. And the Ojai R30 Expansion Kit avoids power fluctuations for consistent performance.
