Above is the circuit diagram and Vero layout for the Distortion pedal, the component values are included in the circuit and there placment can be seen from the photo of the board..
Test Tests.
Power requirements for the Distortion Pedal is either a plugpack 9V to 12V or a 9V transistor battery. A maximum of 12V is advised.
The bias voltage for all of the opamps is derived from a voltage divider consisting of two 10K resistors that provide a mid voltage point, this voltage is then amplified through an opamp to lower noise introduced by the resistors, the output of this opamp is the bias input for the other opamps..
