Up for sale, a Moog Moogerfooger MF-101 Lowpass Filter in excellent condition and in perfect working order, complete with a box, user manual, and power adapter. This discontinued, much-lauded all-analog lowpass filter was designed by Bob Moog and his engineering team in the late ‘90s and is a direct descendant of the original Moog modular synthesizers, delivering the same analog functionality and versatility as those iconic units. This particular MF-101 was produced under Bob Moog’s Big Briar brand prior to Moog’s repurchasing of the official Moog branding rights in ‘02.

The MF-101 pairs two complete modular functions, boasting a Voltage-Controlled Lowpass Filter (the classic Moog “Ladder” filter) and an Envelope Follower. The interplay between the two enables a wide array of tonalities, enabling the filter to be dynamically “played” via the dynamics of each sound. The harder you play, the more the sound is affected, resulting in a notably musical feeling effect and tones that range from subtle smoothing to more dramatic compressed sounds. All performance parameters are voltage-controllable, enabling the usage of expression pedals, MIDI-to-CV converter, or any source of control voltages. To that end, there is a whole suite of independent CV/expression pedal I/Os, enabling the independent manipulation and control of each parameter while also providing modular interconnective between other similar analog effects.

Cosmetic touches include wood endcaps, orange switches, clean silkscreen graphics, and reflector cap knobs. There are just a few minor dings on the endcaps and scuffs on the baseplate, with sparingly little wear on top.

A Moogerfooger box is included (for an MF-103), along with the original user manual and power adapter.
