Voltage Controlled Vintage Fuzz
The Black Cat Monster K-Fuzz Eurorack module processes audio input signals through a modified vintage fuzz circuit to create an array of harmonically complex tones and textures. The brainchild of vintage synth collector Tom Hughes, the Monster K-Fuzz module has been adapted and optimized specifically for use with modular synthesizers. The Monster K-Fuzz module features variable controls for Saturation and Frequency, 3-position selector switches for Clipping and Voicing, and two separate Voltage Control Inputs.
