Designed by Bob Moog, the MF-103 is comprised of two complete modular functions: a 12 stage phaser with resonance that allows for perfect tonal impartation and and a wide-range LFO capable of generating sedate surges and swells to percussive percolations and complete sonic destruction. To further expand on this classic modularity, the MF-103 contains multiple CV/Expression Pedal inputs and outputs. This allows each parameter to be manipulated and controlled simultaneously, while also providing modular interconnectivity between other Moogerfooger analog effects.
