Isolated Power

Zuma is the highest horsepower, most technologically advanced effects pedal power supply of its kind. Zuma offers nine high-current, individually isolated, ultra-low-noise outputs—each with its own dedicated regulator and custom transformer. Designed to meet the needs of today’s players, each output provides a staggering 500mA of current.
Zuma’s dual-stage topology, pre-regulated outputs, optically isolated feedback, and advanced multistage filtering result in a power supply that allows your pedals to achieve their highest possible dynamic range.
