Moog Music MF-102 Moogerfooger Ring Modulator Pedal

No longer available at zZounds
Get three modular effects in one pedal, including a ring modulator, a voltage-controlled carrier oscillator, and a voltage-controlled dual-waveform LFO.

The MF-102 Ring Modulator is a direct descendant of the original Moog modular synthesizers. It contains three complete modular functions: a ring modulator, a voltage-controlled carrier oscillator, and voltage-contolled dual-waveform LFO. It can be used to process any instrument-level to line-level signal.

A ring modulator produces sum and difference frequencies between the audio input and a carrier oscillator. The ring modulator's LFO can be used to modulate the carrier frequency. The moogerfooger ring modulator can create effects ranging from subtle tremolo to harmonically rich distortion, gong-like sounds, sweeps, swoops, and divebombs. It can be subtle, or outlandish in it's use - you decide!

The moogerfooger ring modulator's control parameters are signal mix, carrier frequency, LFO rate, and LFO amount. All of the ring modulator's parameters can be controlled by the great feeling knobs that beg to be tweaked as well as with expression pedals or external control voltages. Panel switches select LFO waveform and carrier frequency range. 1/4" jacks are provided for audio input and output, pedal/control inputs, carrier input and carrier output. The heavy-duty yet smooth acting bypass switch allows tabletop or floor use.

Imagine that the ring modulator's carrier oscillator is producing a 500 Hz sine wave, and your input signal is a 100 Hz sine wave. The ring modulator's output will be a complex waveform. You will hear two pitches: 400 Hz and 600 Hz. You will not hear your original read more input or the carrier oscillator.

Features:

- FREQUENCY rotary control, which varies the carrier frequency over a six-octave range.
- RATE rotary control, which varies the LFO's frequency from 0.1 Hz to 25 Hz.
- LFO AMOUNT rotary control, which adjusts the amount that the LFO output sweeps the carrier oscillator.
- MIX rotary control, which crossfades continuously from unmodulated to modulated audio.
- DRIVE rotary control, which adjusts the gain of the audio input.
- SQUARE-SINE rocker switch, which chooses the LFO waveform.
- LO-HI rocker switch, which chooses between the low frequency carrier range (2 Hz to 130 Hz) and the high frequency carrier range (60 Hz to 4,000 Hz).
- LEVEL, a three-color LED that is used to set the DRIVE control.
- LFO, a LED that indicates the LFO rate.
- BYPASS, a two-color LED that tells whether the ring modulator is on or bypassed.
- ON/BYPASS, a rugged, smooth-acting 'stomp switch.'

"Moogerfooger Ring Modulator: best thing ever, or something..."

This is not something I could replace. You CAN'T replace this. Nothing out there comes close to being like this. As well as the other 2 Moogerfooger pedals I have. They're not just individual pedals, but a system.

Sound
If you know what a ring modulator does, you won't be disappointed. Moog's attention to detail is just beautiful. And the LFO (what i mainly use the pedal for) is one of the best-sounding effects ever.

Features
As with all of the Moogerfooger pedals, the inclusion of modular jacks take it beyond a mere pedal. It's very powerful this way. And while expression pedals are extra, you can get them and are able to control each knob with your foot, which is very nice. But the fact that you can treat a group of pedals as modular components, possible to connect together in a number of ways as opposed to merely a series of individual stompboxes is revolutionary. It gives the guitar (or whatever you run through them) the power of a modular synthesizer. It's not merely an effect that does one thing. You can actually use your imagination and take its functions to completely new levels.

Quality
This is a quality piece of machinery. Once again, following the fine tradition of Moog products. It's sturdy, they use quality components. Many of Bob Moog's original modular synths function to this day. It's due to the same quality and care as he's always put into his products. I know I'm sounding read more like a commercial, but this is really well-made gear.

Value
Okay, I almost put a lower score on this one because it is really expensive. But I still must give it a 10 because it is worth every penny. It's expensive, but there's a reason. The quality in sound and in the way it's built is unmatched! Not to mention the modular expressiveness that these pedals have not found from other companies. So the price is high, but so is the value. This is really the top of the line.

Manufacturer Support
Perhaps the fact that I haven't had the need for support or service says something. I'm pretty sure they have good customer support, but I'm not the one you should really listen to on that since I don't really know myself.

The Wow Factor
If you've heard this you'd know it's one of the coolest sounding things ever! On the issue of "color" and all that, i don't really think that's much of an issue, but I'll address it anyway. I love the way these pedals look. They have that Moog look, which is nice. But if you've read the rest of what I wrote, I think I've covered most of the whole "I Want It" issue. Everything about it is sheer genius.
