Strymon Ojai Pedal Board Power Supply

The Ojai Power Supply, from Strymon, is the best solution to power a handful of pedals, especially high-end boutique pedals that require high quality and clean power. The Ojai has five high-current outputs that are individually isolated, (each with their own dedicated regulator and custom transformer,) to prevent signal noise. There is 500mA of current available for each output. This high quality low noise power allows one to ensure the highest possible dynamic range.
