Chow Centaur is a free distortion effect plugin by ChowDSP modeled after the Klon Centaur overdrive guitar fx pedal.
The plugin contains two modes, “Traditional” which uses traditional circuit modeling techniques, and “Neural” which uses a recurrent neural network to model the gain stage from the original Klon circuit.
The model is implemented as an audio plugin and as a guitar, pedal-style effect embedded on a Teensy microcontroller.
This work began as part of a class project for EE 292D at Stanford University.
The plugin is available as VST, VST3, AU and standalone for Windows and macOS (M1 Macs NOT supported).
