Like an analog synth for your guitar, bass, or whatever.

A high-quality effect designed by Bob Moog, the Moog Moogerfooger MF-103 pedal contains an amazing-sounding 6- or 12-stage phaser circuit as well as a wide-range LFO with an adjustable sweep function. Used with guitars, basses, keyboards, samples, or recorded tracks, the MF-103 can apply subtle tonal coloration or extremely deep phasing that spins your speakers and ears out of control. Uncontaminated by the digital world!

A direct descendant of the original Moog modular synthesizers, yet can be used with any instrument level to line level signal. Sweep frequency, resonance, LFO rate, and LFO amount can be controlled by great-feeling knobs, expression pedals, or external control voltages. Panel switches select range of LFO rate and 6- or 12-stage phasing. 1/4" audio inputs and outputs, pedal/control inputs, LFO out, and auxiliary sweep input for bi-phase effects. Heavy-duty yet smooth-acting bypass switch for tabletop or floor use.

A phaser is a type of comb filter, so called because its frequency response has several dips and peaks, like the teeth of a comb. As the phaser response sweeps back and forth across the frequency spectrum, the harmonics of the audio input signal are alternately increased and decreased. This produces the classic phaser "whooshing" sound.

Phasing is one of the best ways to impart motion to a track and to make sounds come alive. You can get swirling, shimmering, vibrating effects; fill up a whole stage from one sound source; and create brand-new sonic textures.

The MF-103's 2 comb-filter responses are called 6-stage and 12-stage, because of the number of phase-shifting circuits that are used internally. The 6-stage mode has 3 dips in its frequency response, while the 12-stage mode has 6 dips. These 2 modes have distinctly different sound qualities. In addition, the MF-103 features a variable feedback circuit which increases the resonance or depth of the phaser sound.

Best of the Best Phaser

By Joshua Rodriguez

from Los Angeles, CA

Comments about MF-103 moogerfooger 6/12 Stage Phaser:

As far as phasers go, this pedal is definitely one of the richest-sounding and most premium I've ever played. You can get really thick, spacey sounding phasing that's very warm and analog sounding. Adding an expression pedal or connecting it to other Moogerfoogers allows for even more control over the sound. It can be a subtle shimmer if you want, but can also dial into massive, mind-bending, jet-plane kind of stuff. The downside of this pedal, though, is that it works a lot better for the studio musician or the practice studio than playing live. The construction is sturdy enough, but the massive size of the pedal, combined with its price, means that you might not want to haul it to all your gigs. It also runs the risk of being overkill if all you want is a little bit of a phase sound in a verse of one song, or some minor use like that. Still, though, the sound and options of this pedal are incredible, and if you like a lot of phase (like, say, John Frusciante, who uses these), then this is probably as good as it gets - easily another level compared to the Small Stone or Phase 90.
