Warm Audio Mutation Phasor II Guitar and Instrument Effects Pedal

Bring the legendary swirl and wobble of 70s phasing to your rig with the Mutation Phasor II, a faithful recreation that captures all the vintage vibes of the original electro-optical phase shifter. This ultra-analog pedal adds instant funk, depth, and lush modulation to guitar, keys, bass, or any instrument you plug into it. Built with premium components including classic RC4558P op-amps, vintage-style diodes, carbon resistors, and film caps, the Mutation Phasor II stays true to the original circuit specifications while housed in an ultra-tough steel case for road-worthy reliability.

The authentic control set gives you complete command over your phasing effects. The Depth control varies the sweep range width for ultra-rich swirly modulation, impacting higher highs and lower lows as you increase the setting. Speed (or rate) adjustment lets you dial in anything from subtle 1/10th sweeps per second wobble to intense 18 sweeps per second modulation. The Feedback control adds electric feedback to the wet phase-shifting signal, creating more intense phase sounds with particular emphasis on the sweeps that becomes especially noticeable at slower rate settings.

Like all Warm Audio gear, the Mutation Phasor II is meticulously hand-tested and inspected by trained technicians with a passion for making music in Austin, TX USA, ensuring studio-quality sound in every unit.
