Mutation Phasor II
Electro-optical phaser recreating the Mu-Tron Phasor II with Depth, Feedback, and Rate controls for lush vintage modulation.
The Mutation Phasor II is Warm Audio's meticulous recreation of the legendary Mu-Tron Phasor II—one of the most desirable analog phaser circuits from the experimental era of the 1970s. This electro-optical phaser delivers the rich, musical modulation that made the original a studio and stage staple.
Built with premium components including classic RC4558P op-amps, vintage-style diodes, carbon resistors, and film caps, the Mutation Phasor II captures the original's subtle, musical phase effect. Unlike more aggressive jet-plane phasers, this circuit adds tasteful modulation that enhances rather than overwhelms your tone.
The Depth, Feedback, and Rate controls interact in musical ways, from subtle waves to sweeping psychedelic textures. Artists like Billy Corgan, Tom Bukovac, and Robin Trower have relied on this circuit's unique character.
