A re-invention of Moog Music’s classic MF-107 analog effects pedal. The MF-107 FreqBox, originally introduced in 2007, contained several complete modular synth functions: a voltage-controlled oscillator (VCO) with variable waveshape capable of being hard synced and frequency modulated by the audio input, and an envelope follower which allowed the dynamics of the input signal to modulate the frequency of the VCO. In addition, the amplitude of the VCO was controlled by the dynamics of the input signal, and the VCO could be mixed with the audio input. A direct descendant of the original Moog modular synthesizers, the MF-107 was adapted to process, modulate, and play with inputs ranging from guitar, voice, and synthesizer to any imaginable audio source.

The MF-107 FreqBox has been meticulously recreated as the MF-107S, capturing not only the jagged, freaky sounds of the original, but also the organic way in which the parameters interact to create a musical playing experience.
