As a musical instrument brand, NUX already built lots of pedals and multi-effects. For users who use high gain distortion pedals always have headache with the power supply. The DC daisy-chain can drive several pedals, but the ground noise will occur easily especially while you connect analog pedals and digital pedals at the same time. To be an industry pioneer, NUX has the mission to build a reliable, extreme-low-noise, light-weight, universal power, high current, all-isolated power supply.
