Guitar OmniDrive effect


Posted on Jan 4, 2013

This is a versatile distortion pedal. Think of it as analogue modelling, using analogue circuitry to model a wide range of analogue distortion devices. It includes the main elements found in the majority of distortion boxes. The unit comprises four sections: A pre-amplifier with switchable treble boost. A switchable low pass filter. A switchable full wave rectifier for octave-up effects. A clipping stage with variable gain and two clipping modes.

These stages are combined with level and tone controls to allow emulation of most of the multi-stage overdrive and fuzz units. The rotary controls are drive, tone, blend and volume. The switches are treble boost, low-pass filter, octave up and distortion mode. I have also added an optional scoop switch to the tone control circuit. This cuts the mid-range and should be popular with death metal noise vandals. I suggest mounting the clipping diodes via a 3.5mm miniature break jack. That way you can insert little plugs with germanium diodes or asymmetric diodes or whatever in them.
