the moogerfooger mf-103 is a voltage controlled phaser with switchable 6-stage/12-stage modes. it also incorporates a voltage controlled triangle-wave low frequency oscillator. this lfo is routed internally to modulate the mid-phaseshift frequency. the moogerfooger phaser is heavy competition for standard star-fleet equipment, as its modulation amount is continuously variable from 'stun' to 'kill' ;-) (see markings at 'amount' control)

the rear panel offers lots of jack sockets for audio and control signals - in addition to the usual signal inputs and outputs, the output of the lfo is also available on a separate socket. the lfo signal can be replaced by another signal of your choice for still more complex phase modulations. when the unit is switched to 12-stage mode, it is even possible to leave the control of 6 stages (corresponding to 3 frequency peaks) to the internal lfo while an external modulation signal controls the other six stages, providing very complex modulations. this is furthermore interesting as there is also a second output jack (marked 'aux') which carries the 'inverted' phased signal for really weird stereo-field manipulations including 'rotating-speaker' simulations.

there are five input jacks altogether for control voltages, so the unit can be connected to foot pedals or other controllers - for instance other moogerfoogers or any synth or even modular synth gear with cv interfacing.

the moogerfooger is a very versatile phaser, offering more voltage control than most modular phasers. it can produce a wide range of phasing characteristics, while it sounds very warm, smooth and precise, also very clean.
