The compact and convenient Ojai effects pedal power supply puts Strymon-quality power in a unit that fits in the palm of your hand. Despite its size, the Ojai boasts five 9-volt outputs rated at 500mA. Each output delivers noise-free operation because of Strymons dual-isolation design. And utilizing the units 24-volt thru allows you to expand with another Ojai or to match yours with the larger Zuma power supply (sold separately). The Strymon Ojai power supply is built rugged and is one of the most convenient supplies out there.
