Difference in wiring schemes?

Fixing to replace the pots in my P bass since they're getting scratchy.

I'm accustomed to soldering the tone cap to the back of the tone pot and the side lug like so:

but I've come across some diagrams that have the tone cap going between the volume and the tone pots:

What is the difference, if any?

Defer to others who are more expert but I don't see how this would have much effect on the tone. A tone pot works by sending some of the signal to ground. The frequency of the signal is dependent on the resistance of the pot and the value of the resistor used.
Some circuits put a resistor between the volume and tone pots to keep the signal more consistent when you lower the volume via the volume pot on the bass.
I look forward to explanations if I am wrong.

They are electrically the same. In both cases the amount of signal that goes through the cap is controlled by the pot. In one case the restistive restriction is before the signal gets to the pot, the other after. But it's like a hose - you can control how much water is dispensed by turning down the tap at the house connection, or by adjusting the amount of flow at the nozzle. Same difference.

Yeah after a cup of coffee I realized they did the same thing, just cap position was a little different.

Same, except there is no signal ground connection between the tone pot case and the volume control in the first diagram.

I suggest diagram 1. Diagram 2 fails almost immediately (especially without pvc on the cap legs) when potentiometers start to spin from use/undertighting/loosening over time.

Good point! I ended up trying out the 2nd one just because I wanted to try it, but I'll keep that in mind going forward.
