Moog MFS-RING-02 overview

  • 1Description

With an updated look from the original, the MFS-RING-02 Minifooger MF Ring Pedal from Moog is an analog ring modulator for guitar and bass that is modeled after the Moogerfooger MF-102. The pedal works by outputting the sum and difference frequencies of your instrument, and a carrier oscillator. It allows you to create sounds from octaves to choral dissonance to harmonic undertones, as well as synthesized bell-type sounds and synth-style leads.

The pedal has an expression pedal input, allowing you to use an optional expression pedal to control the frequency level. Use it for sci-fi swells, bit reduction effects, whammy dives, and more. This input is additive and will allow you to go past the normal panel settings. The pedal can be powered by either a 9-volt battery or with an optional power supply.

FREQ: Tunes the frequency of a carrier oscillator to the root note in a scale. The range of this control has been refined to be extremely musical. At lower settings, chorus and octaves occur on notes within a chosen scale, while beating and extreme dissonance occur on notes played outside of that scale. At Mid position, the sound is buzzy and tight. This is great when paired with the MD Drive for octave-fuzz sounds. At the maximum position, the sound is much more synthesized and robotic

MIX: Sets the amount of input versus modulated signal. A ring modulator outputs the sum and difference frequencies of your instrument, and a carrier oscillator (FREQ). At lower to medium levels, the MF Ring can be used to accompany and accentuate notes. As Mix is increased, you will notice more synthesized and bell-type sounds. At maximum, the input signal is completely gone and only the sum and difference frequencies are heard. This is perfect for creating unpredictable synthesized and electronic sounds

TONE: A filter circuit only applied to the effected signal. This allows you to leave in the MF Ring’s natural high frequency chime and buzz, or dial it down for a warmer, more musical character. Because the tracking of the MF Ring is so accurate, this control is particularly useful for dialing in sounds that accompany lead lines, bends, and even chords. It is the perfect way to add unique texture to an idea without it overtaking the sound of your instrument

EXPRESSION PEDAL INPUT: This input is assigned to the Freq control. Use it to specify two independent playing keys or create classic sci-fi swells, bit reduction effects, and whammy dives. This input is additive and will allow you to go past the panel settings

    Moog MFS-RING-02 reviews

    MFS-RING-02 Minifooger MF Ring Pedal is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Ringing in the New Year! Bought for use at live shows. Haven't done that yet but a good time learning the parameters. Great, bent tones coming out of this lil' monster. 9 volt battery or specified Moog power adapter keeps the tones flowing. Recommended.
