HSS 250K and 500K vol pot

[dosmun]

I am trying to wire up a Strat with a HSS config (5 way switch) but I want to be able to have a 250K pot for the singles and a 500K pot for the HB. I tried the wiring diagram on guitar nuts.
The HB is just to dark and muddy sounding this way. I am presuming this is from the 2 volumes being in parallel.

I don't necessarily need 2 volumes. Would wiring a 500k resistor from ground to the the neck+ and mid+ give me the 250k on the singles when switched to those positions? It seems like it would work on paper but I would like a second opinion before I tear everything apart again.
I am referring to this diagram for my idea.

Thanks

Yep. Good presumption and understanding.

Sort of.

While it will effect a parallel combination of 250K Ohms, the rotational effect of the 500K volume pot will still differ from a 250K one.

For example, when the 250K one is at half value (about "8" on an an audio taper pot in a Strat), the effective Thevenin (Wiki it) series output impedance from the pot will be about 63K (both halves of the pot in parallel).

With the 500K one at half value, the effective series output impedance from the pot will be about 125K.

The volume pot will have a slightly to fairly different mid-span control response.


But, it will be less muddy (500K vs 167K in parallel across the humbucker as compared to what you now have/had).

(And, potentiometers are variable. )
