I have a project with a two pickup guitar which I want to have: a dedicated tone (treble cut) controls for each pickup; with a single, global volume control; and, a typical 3-way toggle pickup selector switch:. BUT I keep finding different wiring diagrams for how to achieve the above. Please refer to the three wiring methods show below. How do these differ electronically? I don't understand. Which one is the 'best' or the most desirable? Are all of them perfectly viable? thanks    |

From what I see there they are the same (the first two are exactly the same but only relocates the connections, and the third one swaps the location of the cap and the pot but since they are in the same series circuit it makes no difference).
The differences seem to be based on convenience as to where you want to put things physically for ease of soldering and assembly and wire routing, but I see no other differences (unless I missed something in my rather quick look I had at them).

One more thing: the ground connection should be routed without forming a ground loop, although this is sometimes trick to achieve in practice for actual wiring.

This ^ #3 is a particularly bad choice in terms of physical durability. |

Yes, agreed for sure.
I would never use a capacitor to support that wiring in mid-air. I would suggest that you totally discard #3, as I cannot see any benefit for it that outweighs the increased risks.

thanks for the replies, all.

Even though this has been correctly answered, let me just say that all three wiring diagrams come from just one schematic. Stated another way, a schematic that illustrates a circuit can be physically implemented in a large number of ways.
Thinking about what parts to use and where to put them, that's the job of a wiring diagram. That's why we separate the two images - one is ideal for drawing up a logical solution to a problem (or achieving a goal) without having to think about the parts themselves; the other makes a physical reality out of that design. (Or more to the point, at least one of several possible wiring lash-ups.)
