2.2M in/out resistor in rangemaster question...

Hello all

This is a very basic doubt that I have;
I'm building  a rangemaster, and I'd like to add the 2.2M pulldown resistors at the in/out to avoid pops.
As far as I know, the resistor should connect to the signal path to the ground;
Attached, I've placed the great Dragonfly layout - and I marked a supposed placement for the resistors. Is the marked place a good one?
Can I solder the resistor accross the jack lugs? Another suggestion?



Thanks a lot... sorry for such a beginner doubt.

  I would move each 2m2 'up' one switch lug each.
  Just outside the circuit [outside the input and output caps], they will 'drain' whatever the DC blocking caps could store [if 2m2 is small enough depends on how leaky the caps are, probably fine there] so that there's not a voltage change on the signal path when the bypass switch is used [pop].
  You don't really want or need pulldown resistors to be part of the bypass circuit through the box, although 2m2's divide to 1m1 total R to ground, which won't drain much signal in the bypass mode, if you do this on more than one pedal it [the total R values combined] may start dividing the signal down in the bypass mode....
  anyway no reason to want that, connect the pulldowns to the circuit side of the switch on the switch or on the circuit board.
Convention creates following, following creates convention.

thanks for the answer...
just to confirm, I've posted another image. Is this one ok? Should I do it like that?



thanks again...
