Smoothie Pedal

I hear the swirling noise change in the white noise coming through the amplifier, but there is still not guitar with it. There are also slight cracks and pops when testing.

Well sounds like it is time to build up an audio probe/test rig so you can trace signal to hear where it is going south in the circuit path.

If you have the pedal building bug then you really will need to build up a basic test rig either way so know is a good time. Here is a crude one you can build up at minimal cost using an old or scrap enclosure.

Also if you have not done so. disconnect your pcb in/out wires on the 3pdt switch and run them directy to the in/out jacks direct (thus bypassing the switch altogether) to rule out bad switch.
