Description

Warm Audio Mutation Phasor II - Electro-Optical 6-Stage Phaser with Feedback

The Mutation Phasor II is a true-to-original recreation of the classic 1970s electro-optical phaser circuit. It brings swirling, psychedelic tone to your pedalboard while maintaining flexibility for modern use. Use it with guitar, bass, keys or any audio source you want to warp.

Deep Modulation with Feedback Control

With controls for Rate, Depth and Feedback, you can dial in anything from gentle movement to dramatic, resonant phasing. The feedback circuit enhances the intensity of the effect, especially at slower speeds, giving you expressive “woosh” textures and vintage character.

Professional Design & Operation

Built with premium components like RC4558P op-amps, vintage-style diodes, and film capacitors, the Mutation Phasor II offers reliable 100 % analog performance. It features buffered bypass, a rugged steel chassis, and is powered via 9 V battery or external regulated 9 V DC (centre negative).
