What does the 22K on the output of the Guvernator do?

[HamishR]

Seem to have asked my question in the title... Pin 2 of the volume pot often goes to output on an OD pedal, but this time it goes to out via a 22K resistor. What does this 22K do? What would happen if you took pin 2 straight to the output?

Thanks!

I believe the 22k resistor with the 470pf capacitor creates a low pass filter (corner frequency around 15Hz) which is used to filter unwanted noise or hiss from the circuit. Keep in mind I’m not a EE, but a pharmacist.

Haha! And I'm no EE either but a photographer, which at one time wasn't so far off being a pharmacist. Now some rock stars are closer to being a pharmacist than I ever was.

I had a feeling it would be some kind of filter but what sort I couldn't say.

Sorry. Corner frequency is 15kHz.
