Analog Phaser. Electro-optical phase shifter pedal with feedback loop. Controls: Rate, Depth, and Feedback. Buffered bypass. Phase shift: 1 Hz - 18 Hz. RC4558P operational amplifier, various vintage diodes, and hand-selected film capacitors as well as carbon resistors. Signal-to-noise ratio: 86 dB at 2 V input. The Mutation Phasor II by Warm Audio is inspired by the phaser sound of the experimental era of the 1970s. This effect pedal produces legendary vintage vibes and adds rich bass, wobble, and swirl effects to instruments like guitar, piano, or bass, giving the sound an instant funk character. The electro-optical phase shifting pedal is an authentic replica of an iconic pedal from the 70s, built with high-quality components. True to the original, the Mutation Phasor II delivers a psychedelic sound appreciated by musicians and producers such as Billy Corgan, Tom Bukovac, Robin Trower, and many others. Maximum Depth. The Depth control allows you to vary the width of the sweep range to achieve deep modulation. Increasing the Depth control expands the frequency range of the effect, impacting both highs and lows. Depth Switches. The Depth control can also adjust the speed of the phase shift effect to create more or less wobble in the sound - from 1/10 sweeps per second to 18 sweeps per second. Feedback. Increasing the Feedback control adds electrical feedback to the phase shift signal. Raising the Feedback control produces a more intense phaser sound with a special emphasis on the sweeps. Studio Sound. The Mutation Phasor II is made from top-quality components, including classic RC4558P operational amplifiers, vintage-style diodes, carbon resistors, and film caps - housed in an ultra-durable steel case with a vintage look.
