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.
