Timbre Modulator

Based on Electronotes #72 design by Bernie Hutchins. This circuit implements "voltage controlled distortion".

  • Clipping level independently adjustable on positive or negative halves of input waveform
  • Input drive to diode clipper is determined by modulation CV
  • Unmodified signal can be summed with clipped signal

  • PCB built and stuffed
  • PCB tested and working
  • It's kind of hard to explain what this one will do to the sound, but I can get a very believable tuba sound out of it with a sine wave input.
