The MF-103S 12-Stage Phaser is a re-invention of Moog Music’s classic MF-103 analog effects pedal.

The MF-103 12-Stage Phaser, introduced in 1999, contained two complete modular functions: a 6-stage/12-stage voltage-controlled Phaser and a voltage-controlled wide-range Low Frequency Oscillator (LFO). Designed by Bob Moog and his engineering team, the MF-103 was a direct descendant of the original Moog modular synthesizers, adapted to process, modulate, and play with inputs ranging from guitar, voice, and synthesizer to any imaginable audio source.

The MF-103 Stage Phaser has been meticulously recreated as the MF-103S, capturing not only the psychedelic enveloping sound of the original, but also the organic way in which the parameters interact to create a musical playing experience.

With CV interconnectivity, stereo functionality, an extended feature set, the ability to run multiple instances, and presets, the MF-103S plug-in further tailors the classic Moogerfooger functionality to the modern digital creator.

The MF-103S also introduces unique features not seen on the hardware instrument, including:

OUTPUT MODE recreates the original MF-103’s MAIN and AUX outputs and allows you to route those in STEREO configurations.

LFO TYPE switches between the MONO LFO of the original or creates a second inverted LFO for STEREO modulation.

The MF-103S 12-Stage Phaser offers CV Inputs for LFO Rate, LFO Amount, Resonance, Phaser Sweep, and a second Sweep input to modulate the two sections of six stages independently, as well as the capability to attenuate or soften these modulations.
