Wiring/Eletricity question

[CarrierWave]

Hello TDPRI

My question is whether this wiring scheme will work:



Based on my absolutely awful knowledge of electricity, this circuit wouldn't produce any or little sound because there is a short path to ground whenever one of these pots is turned fully so that its path to ground has zero resistance. (set at 0.) I don't have any faith in my understanding though hence prior to experimentation I have come here.



On this other diagram, the output of the volume pots connect to different lugs of a DPDT on/on/on switch, so there is no shared connection between two volume pots. If this diagram had a 5 way switch it would be more helpful, because essentially what I need to know is what happens when you combine two signals coming from two pots that both have a path to ground.

I am using individual switches, but they are wired before the volume pots come into play, because they need to divert up to another mid boost circuit that uses a 50k volume instead of a 250k. I won't clutter up the idea with or annoy anyone with that though.



On this diagram the pickups run into the "input" of each of their pots, but then oddly the middle pickup's output from the volume pot connects to the output signal from the switch. So to me, when ever the middle pickup volume pot was at 0, his entire signal would escape to ground. Yet it doesn't... apparently... so why not? Wouldn't the middle pickup be always in the mix irregardless of the switch position? Is this guy's diagrams whacked or am I not understanding something about potentiometer construction?

If anyone has a clever idea of how to do this, or reassurance that this circuit will work, I'd be extremely pleased. Thank you all.

If you have advice on where to ask this question that'd be good too!

Your diagram appears to be drawn viewing the pots from the control shaft side. If this is correct, then it oughta work. Any pot that is turned down will be sending the individual pickup's output to ground, but will still allow the others to work.

Thank you for your response. I got visual and hands on with a borrowed multimeter and realized how the wiper on the pot works. Lug 1 and 3 always have 250k resistance because of the way the pot is built, so that solves my problem right there. Thanks!

I realized that the 2nd diagram is an Epiphone P93, which does have the middle pickup always on, and I realized why the entire signal wouldn't escape to ground through the middle pot.
