Some people leave them out of the circuit, so obviously it works without them - so what differences do they make? How do they affect the sound?

My simplified understanding:
Filter with cap/resistor - changes the EQ of a pickup. Actually reshapes the tone instead of just filtering out highs like a typical tone control. Changing the value of the cap or resistor changes the effect, also. Filter without cap/resistor - lowers the impedence, effectively making a higher output pickup sound like a lower output pickup. Once I get my new computer (c'mon tax return  ), I plan to record a demo of this setup. It's very cool.--Garrett--

Thanks, Garrett, that does make it clearer to me. I think I'll go for the "vanilla" effect, since I don't use tone controls very often anyway. What I'm mainly after is a way to tone down some high output humbuckers without replacing them.
I'd like to hear the demo when it's done. |

I used only resistors to fix the level of inductance lowering.
It was try and check approach with several resistor values, so basically PU can deliver two (or more) basic sounds (depending on switch and number of combinations with resistor used). Caps are later part of master tone control. |
