Moog Moogerfooger MF-104

MF-104 Image

The Moogerfooger MF-104 Analog Delay is a limited edition offering from Bob Moog and Big Briar (now Moog Music). This excellent little tool is an authentic analog delay device with a delay range of 40 milliseconds to 0.8 seconds. This is perfect for re-creating an analog slap-back echo effect. Because it's analog, it has a very warm overtone that's nicer than most digital delays.

There are three main knobs to adjust delay time, feedback and wet/dry mix. Each of these parameters can be externally controlled by control voltage or expression pedal. Additional knobs to adjust the Drive or gain of the audio input to the delay, Loop Gain which sets the gain of the external feedback loop, and the Output Level knob are also available. So why is it a limited edition? Big Briar has secured a supply of the last analog delay chips and so only about 1,000 units will be produced. Get yours from Moog Music while they last! It is used by Stereolab and Air.

Can this pedal be used for vocals? As in, can I plug a vocal mic into it and delay my vocals?

I don't think this thing can be beaten in any realm except cost. If someone could make something for $200 that was close to this moog might see some competition. I did a video review of mine for guitar, check it out here:

So I got to use my friend's moogerfooger echo, and he also had a lowpass filter moogerfooger and I think it was the phaser moogerfooger too. WOW I don't think many people realize what these pedals can do.... First of all you can have (wah type) pedals attached to EVERY knob on each pedal. so one for feedback one for delay time...etc which makes them extremely versatile in a live/improv setting. not to mention really spacy but controllable in a show or recording situation. Also you can jack the knobs of two pedals together or two knobs on the same pedal together and one knob now controls both.

Nice analog delays, the foogers are a bit trendy, since you can get a true bucket brigade delay for 150-200 that sound fantastic (600ms or so) and wont break the bank (although this is the only 1000ms analog delay). Keep an eye out for a used one, i snagged one for less than half price. Note that the "long delay" switch delays are extremely murkier than the "short delay" switch. The CV ins/outs are the bees knees, especially if you have other foogers or cv gear.

Too expensive for what it does and not as good and crazy as an old ROLAND analog delay ... I sold mine, trendy [beep]
