  • The MF-101 Lowpass Filter is a direct descendant of Moog modular synthesizers designed to work with any sound source.  This all analog instrument is perfect for thickening synths, funkifying bass guitars, distorting drum samples and smoothing out harsh sounds.  

    Designed by Bob Moog, the MF-101 is comprised of two complete modular functions: A classic Moog Ladder filter section for sculpting and refining your own unique tone, and an envelope follower that allows the filter to be dynamically “played” via the dynamics of each sound. The harder you play, the more the sound is affected. To further expand on this classic modularity, the MF-101 contains multiple CV/Expression Pedal inputs and outputs. This allows each parameter to be manipulated and controlled simultaneously, while also providing modular interconnectivity between other Moogerfooger analog effects.
