DARKADIATOR
The Darkadiator is a discrete (fully transistor based) glitchy and gated fuzz with PWM, octave down and LFO modulation.
This DIY project started as a nerdy personal challenge. I wanted to build the Arcadiator (the same features), but using only discrete components (no IC's - 100% transistor based) and only using common "jellybean" transistors.
I had the complete version running on the breadboard, but I decided to make it a bit different than the original Arcadiator to set it apart and to keep the component count reasonable. It turned out as a very cool guitar synth: The Darkadiator (short for Discrete-Arcadiator, although the final version is quite different).
Features • Either straight square Wave Fuzz, one octave down or both • Two modes: PWM or Lowpass • Width/Cutoff control • LFO modulation: Chop or alternating octaves • Control Voltage input for the LFO speed
