Spirit box pulldown resistors change?

Hey guys!

I’ve built a spirit box and like it very much(even though I’ve agreed to sell it to a friend who likes it more). But it makes quite a rumble when you turn it on. Not really like a regular pop that you often get with true bypass switching. It sounds like you’re moving an amp with spring reverb while it’s on. The pedal has pulldown resistors both at the beginning and end of the circuit. Could changing the value of these do anything with that raucous?
