Alchemy Audio Phasor II

Alchemy Audio · pedal

Alchemy Audio's Phasor II is a faithful clone of the original Musitronics Mu-Tron Phasor II, a classic electro-optical phase shifter from the 1970s prized for a rich, swirling sweep distinct from later, cheaper phaser designs, reissued here in a modern, pedalboard-friendly footprint running on standard 9-volt power. Where original vintage Phasor IIs have become expensive and increasingly hard to source in good working condition, Alchemy Audio's recreation gives players access to that same classic Mu-Tron swirl without needing to track down and maintain a genuinely vintage unit, part of the company's broader specialization in careful reproductions of rare or discontinued effects circuits.
