Moog MF-103 Moogerfooger 12 Stage Phaser
- DESCRIPTION
What is a Phaser? - 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.
What is a 12-Stage Phaser? -The MF-103 produces two comb-filter responses. They are called 6-Stage and 12-Stage, because of the number of phase-shifting circuits that are used internally. The 6-Stage mode has three dips in its frequency response, while the 12-Stage mode has six dips. These two 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.
