The Car Crash Oscillator is based on the crash sync by John Hollis. Much like Tim Escobedo, John has a number of cool, weird and twisted circuits documented on the internet. This particular circuit is the front end distortion of an MXR blue box driving into a 555 timer chip to create a synth like, resetting oscillator effect.
Traditionally the crush effect (the best bit) is controlled by a potentiometer, but I have added a switchable input that also allows you to control this dynamically by an expression pedal.
I recommend also picking up the Johnny Five 3PDT footswitch to compliment this project and provide the LED power indicator function.
