The award-winning Moog MF-101 Low Pass Filter is a successor to the original modular Moog synths, containing two modular functions: voltage-controlled low pass filter and an envelope follower. Use the MF-101 to create dynamic-controlled filter sweeps for your guitar, bass, keys, or essentially any instrument that can be plugged in. You can even choose between brighter 2-pole filter frequency and the deeper 4-pole - the MF-101 tries to give you as many options as possible in building your tone.

  • It's a classic for a reason.

    What can be said that hasn't already - they were made for decades and are staples in most setups of basically any electronic musician (and many guitarists) you can think of. The filter is smooth and has really great knob action (if you care about that sort of thing). The drive alone is great for boo…

  • Made my Korg sound more like a Moog

    Like the title says.... only reason I got it. And it worked, but I still prefer Moog over Korg

  • Put this in front of any synthesizer and it instantly improves it.

    I own a few of these. I have in front of all of my synths (Korg, DSI, Roland). It adds girth, character, warmth, and thickness​ to anything -even at subtle​ settings. I even put it in front of my Moog synths and it sounds better than the on-board filter. This is an absolute gem and a must for any rig or studio. Fantastic build quality. Unparalleled​ sound.

    Much more than just a envelop follower this is one of the most versatile tools for any musical application. Add motion to a sequence or warm up a drum track - freak out any horn. It's cool. It's essential. This is the real R.A. Moog Ladder Filter in pedal. And now they are out of production.

  • Great product!!
