Oddly, the similar-generation SD diagram of the jag has the standard Fender wiring in the rhythm circuit, not the non-standard wiring they published for the same pot in the jazzmaster ...

Huh. At least they've published both...

What would be the difference in variations for the rhythm circuit, sound-wise? Any point to one vs the other? My instinct would be to wire a rhythm circuit the way Fender designed...
Just a mildly informed guess:
- there is more volume loss due to it being wired like volume with resistance in signal path
- there is no resonant peak. Like the cocked wah type effect when tone is very low.
- probably changes cutoff frequencies and amount off attenuation quite differently. A single resistor is different to a potential divider which applies a ratio. The fact there is resistance in signal "pushes" more signal to ground, so yes its likely stronger.

+Notice the Jag lead has an extra resistor. I think it affects taper of the control and basically negates some of the effects of wiring it this way.

Id say its a more perfect lower resonance highpass.

But one of those will reduce volume. You take frequencies, volume reduces.

Unless a big resonant peak is made like by the less natural sounding "regular" two wire way of wiring.

Awesome. Thanks for the reply Jorri!! I'll likely try out both to see what I like, but this is good information. I do wish I had more of a proper electrical theory background sometimes.
