Title: (Guitar's)Tone control - Before or After the Volume?
Post by: jeff on June 18, 2009, 10:49:32 pm
What's the difference in putting a guitar's tone control on the outer lug(pickup side) of the volume control or the output side(wiper)
There should be no difference with the volume full up, but what effect does it have when the volume is rolled back and why?

I can't say as that I've ever noticed a difference, and I've done both.

It really depends on the circuit surrounding the control. In some positions volume controls can react with other components  to form a filter.  This can cause highs to be lost when the volume is turned down.  This is why in KoC designs, he has a lot of fixed resistors between volume controls and tubes.

I'm talking 'bout guitar controls. I've read the gibson's "50's" wiring puts the control after the volume and the "modern" style has it before.

Like I said, I seriously doubt you could hear the difference. 

If you really want to know, install one with a push/pull pot to test it.

Same still applies.  Put a capacitor and resistor together and you form a filter.  Ever notice when you turn down the volume on your guitar and you lose highs? Thats a filter. 

Same can apply to your circuit as well.  However if you dont feel like looking at the theory you'll just have to try for yourself.

I think this addresses your question:  http://www.singlecoil.com/docs/paula.pdf  But I think the wiring diagrams are inconsistent.  If this is what you're looking for Madison, Freshstart, G._Hoffman and I have 2 threads on this lower down on the page in the Guitars Section.  The Topic is confusing and subjective.
