Neurotron kit

The Neurotron is a unique ring modulator and octave fuzz with LFO modulation for a stunning array of tones and sound effects.

In addition to pure transformer-based ring modulation, it also gets into octave fuzz and synth territory. The carrier wave is modulated by an LFO, and it can be used in either PWM (pulse width modulation) or FM (frequency modulation) modes. Expression controls are available for the LFO depth and VCO frequency, and it has both CV input and VCO output for syncing with other effects and external systems.

This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 6 knobs for 6,3mm shaft and 2 knobs for knurled 6mm haft, up to 20mm diameter, separately.
