Vol/tone - series/parallel?

Hi.

I'm preparing long post and one detail got me thinking.
As far as pots are concerned I like to connect signal into lug2 (wiper) and have it send to lug1 when left turned or to lug3 when right turned. That's for logic clarity sake.

Now when you connect the tone pot you can either run the wire from vol's lug2 (clear untouched signal) or from vol's lug1 (lower quieter signal when volume gets down), as in drawing below:


The (A) variation shows it as a literal diagram, but the (B) as a simpler version of it got me thinking.

It seems that running wire from vol's input lug2 to tone (drawing 1) makes the vol/tone connection a parallel relation, and running wire from vol's output lug1 to tone (drawing 2) makes it a series?

Do I got it correctly and does it even matter? If it does matter in any way then how would each of the connection variations affect the tone?

 

I did suspect that theoretically lowering volume in connection no.2 may introduce additional resistance into cap indeed, but didn't expect it to be true in practice.

So basically you say that connections 1 and 2 in drawing below are more reliable (or at least more predictable) than the no.3 , is that correct?


Are vol and tone pots in series to each other?
