pull down resistor question

[csmatt45]

It is ok to take your pull-down from the fx out on your 3pdt to ground. I know electronically speaking, it's the same as the vol pot or board, but I seem to remember reading that there was some reason not to do it that way. Anyone care to comment?

thanks as always!

  Ive been placing my pulldowns right to the switch's circuit input and output lugs.
  I take a couple ~1meg resistors and make a string, twist one end of each together, making a 'V', and soldering the 'tops of the "V" to the switch lugs, the Bottom to a ground, leaving enough lead near the switch to solder the circuit in/out wires to. Seems to work fine...maybe I'm missing something here?

thanks Pete. I am pretty sure it's fine, but I think I read somewhere to do it at the board only. I thought maybe there was something I was unaware of.

As long as you're connecting the resistor between the effect output and ground, it doesn't matter if it is physically connected to this point on the board or on the effect output lug of the switch. 

The thing to avoid, though, is tacking on a resistor across the lugs of the jack, or between the "output" (instead of "effect out") lug of the switch and ground. 

See this thread.

This is a newbie question, but . . . I can solder the pulldown resistor from the effect output lug on a dpdt to the casing of the switch itself, right?  I mean, if the switch is in an aluminum enclosure then the metal casing of the switch is grounding out, too, right?

Technically yes but it would probably best to avoid soldering anything to the case of your switch due to the fact the prolonged heat will most likely melt its plastic casing and screw your switch.

As long as you're connecting the resistor between the effect output and ground?  Why is it the Tonepad project and others usually putting it between INPUT effect  and  pcb ground? This is usually 1 meg why not 2.2 or 3.3meg? Thanks

Why not a few meg? 
For caps with potentially a lot of charge (e.g. 1uF and up), it takes quite a long time to discharge the unwanted signal through the resistor.
1 meg is probably small enough if the effect is going to be off for several seconds.

Brett, Is it ok I used 3.3meg? Thanks
