So Which Volume Pot do you need?

The convention of using 250KOhm for single coils and 500KOhm or humbuckers is a good one though there are exceptions. Both Jazzmasters and Jaguars use 1MegOhm (1000KOhm) pots.
Does this make a difference?
Is that the secret of the offset guitar jangle?
I stopped working on pickups briefly to make a short video to demonstrate the difference between the 3 most common potentiometer values.
