What 3pdt wiring do you use; why?

follow-up Q:

since the volume pot of most effects is actually a connection between output and ground, do you think it is far better to raise that pot's value to 2Meg, instead of soldering in a pull-down resistor for the output connection?
i am what i am, so are you.

Why would you need to raise the pot's value to 2M??? A pulldown resistor is a pulldown resistor. It doesn't have to be 2M. The only reason why we use such large values is so they bleed off less of the audio signal. A 100K pot to ground is an even more effective pop prevention resistor than 2M. To also use a 2M resistor would just be redundant, and replacing the 100K volume pot with a 2M pot would just significantly increase the output impedance of the pedal when not at full volume. Not good for tube amps. Bad idea. If you already have a 100K pot to ground at the output, you already have all of the pop protection you need.

i dont quite get some of your earlier explanation (electronics noob = me  :icon_biggrin:) but the last one was quite simple.

i get it!
i am what i am, so are you.
