The Moog MF-101 is a classic for a reason. This award-winning pedal is a descendent of the original Moog modular synthesizers. It boasts two primary functions: it can be used as a voltage controlled low-pass filter and as an envelope follower with any line-level signal.
All of the pedal’s essential parameters can be controlled via expression pedal (not included), or with external control voltages. Consequently, the pedal works particularly well alongside modular synthesizer gear. The unit’s front panel interface features dedicated panel switches that select the filter mode and envelope follower speed. Additionally, the pedal has 1/4” jacks for audio input/output and a dedicated bypass switch that is ideal for tabletop or stompbox applications.
CUTOFF rotary control, which varies the filter's cutoff frequency over an eight-octave range
RESONANCE rotary control, which varies the shape of the filter's response, from pure lowpass to actual oscillation
ENVELOPE AMOUNT rotary control, which adjusts the amount that the input signal's envelope sweeps the filter cutoff frequency
MIX rotary control, which crossfades continuously from unfiltered to filtered audio
DRIVE rotary control, which adjusts the gain of the audio input
SMOOTH-FAST rocker switch, which chooses between smooth and fast envelope follower response
2-POLE 4-POLE rocker switch, which chooses between 2-pole (bright) and 4-pole (deep) filter frequency response
LEVEL, a three-color LED that is used to set the DRIVE control
ENV, a LED that indicates the strength of the envelope voltage
BYPASS, a two-color LED that tells whether the filter is on or bypassed
ON/BYPASS, a rugged, smooth-acting 'stomp switch.'
AUDIO IN 1/4" phone jack - accepts any instrument-level or line-level audio signal from -16 dBm to +4 dbm
AUDIO OUT 1/4" phone jack - -4 dBm nominal output level
CUTOFF, RESONANCE, AMOUNT, MIX, all of which are stereo 1/4" jacks that accept moogerfooger EP1 (or equivalent) expression pedals, or control voltages from either two-circuit or three-circuit 1/4" jacks
