The MF-102S Ring Modulator is a re-invention of Moog Music’s classic Moogerfooger MF-102 analog effects pedal. The MF-102 Ring Modulator, introduced in 1998, contained three complete modular functions: a Ring Modulator, a voltage-controlled Carrier Oscillator, and a voltage-controlled dual-waveform Low Frequency Oscillator (LFO). Designed by Bob Moog and his engineering team, the MF-102 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-102 Ring Modulator has been meticulously recreated as the MF-102S, capturing not only the spaced-out, retro-futuristic sound of the original, but also the organic way in which the parameters interact to create a musical playing experience. The MF-102S is an AUv3 effects plug-in that requires a compatible host or DAW to function.
