Warm Audio WA-MPH Mutation Phasor II

A 70s Legend for Experimenting:
Add depth, wobble, swirl, or “instant funk” to guitar, keys, bass, or anything you can dream of. The Mutation Phasor II accurately recreates the deep phase-shifting psychedelic modulation of the original phaser made famous in studios during the 1970s.

Maximum Depth:
For ultra-rich swirly phase-shifting, the “Depth” control allows you to vary the width of the sweep range - delivering deep modulation expected from a vintage all-analog pedal. Increasing the depth control adds width to the frequency range of the effect, impacting higher highs and lower lows.

Rate Switch:
Easily change the speed (or rate) of the phase-shifting effect to create more or less “wobble” in your tone - From 1/10th sweeps per second (slowest) to 18 sweeps per second (fastest).

Feedback:
Increasing the “Feedback” control adds electric feedback to the “wet” phase-shifting signal. Increasing the feedback control creates a more intense phase sound with a particular emphasis on the sweeps - Especially noticeable at slower rate settings.

Lush Studio Sound, Road-Worthy Build:
A true-to-original recreation of the 70s circuit, Mutation Phasor II is built with premium components including classic RC4558P op-amps, vintage-style diodes, carbon resistors, and film caps - Housed in an ultra-tough, vintage-vibe steel case.
