Warm Audio Mutation Phasor II Pedal

Among the iconic fuzz pedal creations and reliable delays of the 1960s and 1970s, an electro-optical phaser pedal emerged, setting the standard for lush and funky phase-shifted tones. The Mutation Phasor II pedal by Warm Audio is an exact replica of that same phaser pedal.

It’s built with a heavy-duty stepped metal enclosure, RC4558P op-amps, and premium vintage-style components to perfectly replicate the sound of the original. The 3-knob control scheme (Rate, Depth, and Feedback) retains the original’s intuitive operation. Whether you want to add a funky wobble to your bass lines or create a psychedelic swirl, the Warm Audio Mutation Phasor II pedal is a pedal-sized gateway back to the first golden age of stompbox innovation.
