Moog Moogerfooger MF-101 Lowpass Filter - analog lowpass filter with envelope follower, made in the USA, line discontinued in 2018.

Switchable 2-pole (12 dB/oct) and 4-pole (24 dB/oct). Controls: Envelope Amount, Drive, Cutoff, Resonance, Mix, plus a SMOOTH/FAST envelope switch. CV inputs for Cutoff, Resonance, Amount and Mix plus Envelope Out, so it works as a modular-adjacent processor as well as a pedal.

Condition: excellent, studio use only. All knobs, both orange slide switches and all three LEDs present and working. Faceplate unscratched, silkscreen crisp, wooden cheeks undamaged, all four original rubber feet present. Serial 13857, Made in USA. No scratches, no rash, no corrosion.

Tested 30 August 2026, fully working.

What ships: the unit only - no power supply, no box, no manual.

IMPORTANT, POWER SUPPLY: Moogerfoogers need 9 V DC, centre-positive (tip positive), min. 200 mA, max. 15 V. That is the REVERSE of the usual Boss standard - an ordinary pedalboard supply will NOT work and can damage the unit. Suitable supplies cost about 14 EUR. The polarity diagram is legible on the rear panel in the photos. Note that the original power supply bundled with US units is 110 V and unusable in Europe without a transformer.

Honest note: Moogerfoogers are NOT true bypass - Moog states the signal always passes through the preamp and drive stages.

Ships from Bulgaria (EU), insured and tracked - no import duty and no customs delay for EU buyers.
