Moog’s MF-102 Ring Modulator descends from components in the original Moog synthesizers that sum the frequencies of the input signal and an onboard carrier oscillator, which is itself modulated by a dedicated LFO. The MF-102 affords a varied range of effects—everything from tremolo, harmonic distortion, metallic sounds, and much more… The unit can be surprisingly subtle, or decidedly ostentatious, depending on the user’s preferences.
The MF-102 features an ergonomic front panel with easy manual access to all parameters, which can also be tweaked using expression pedals or control voltages. Like all of the pedals in the Moogerfooger series, the MF-102 features a bypass switch that makes it perfect for both desktops and stomp box use.
Frequency rotary control, which varies the carrier frequency over a six-octave range.
Rate rotary control, which varies the LFO's frequency from 0.1 Hz to 25 Hz.
LFO Amount rotary control, which adjusts the amount that the LFO output sweeps the carrier oscillator.
Mix rotary control, which crossfades continuously from unmodulated to modulated audio.
Drive rotary control, which adjusts the gain of the audio input.
Square-Sine rocker switch, which chooses the LFO waveform.
Lo-Hi rocker switch, which chooses between the low frequency carrier range (2 Hz to 130 Hz) and the high frequency carrier range (60 Hz to 4,000 Hz).
Level, a three-color LED that is used to set the DRIVE control.
LFO, a LED that indicates the LFO rate.
Bypass, a two-color LED that tells whether the ring modulator is on or bypassed.
