It's pretty standard practice to just hang the pulldown resistor across the input jack.

The pulldown resistor "directly" across the input jack? Between tip and sleeve? In case, I guess it's not the best method, because the 1M will be across the ground even when the pedal is in bypass, so that's not a real true bypass.
I think you can do it on the footswitch between the input of the circuit and the ground. I see it on some D*A*M pedal, I think.

I have a generic power filter board I put in things so I generally don't bother adding those parts to layouts. It's also not uncommon to just hang those parts across the power jack.

I prefer have those parts on the main board.

The two extra 1M5 I put in there to terminate the unused section of the opamp to prevent noise. I used the 1M5 because the rest of the circuit uses them on the opamp input positives and if you were building it you'd have a pile of them handy. Using resistors this way is a best practice method for a single supply rail.

Totally clear.

That said, here's a layout with all the doodads.

Thanks for the new layout.
