Has anyone used 4 capacitors in wiring their guitars? Two connecting the lugs on the tone pot to the pot and 2 from the center lugs of the volume pots to the lugs on the tone pots?

I've never tried that.

Re: Capacitors!!!!
Would that hurt in any way or is actually a good idea?

Long story short, it is the way it is because it works best that way.

You only need 1 cap per pot. I don't think having 2 caps in series will do anything to the cutoff frequency or how much is cut off. 2 caps in parallel will add the capacitance amounts, but typically the only way you'd do that is if you were really short of ability to get to a shop and buy the cap you really need.

Re: Capacitors!!!!
actually, I use 2 caps per pot plus 1 on the volume pot.
the volume pot needs one for the treble bleed. the tone pot has 2 because I use a custom made stereo pot with a center detent: sweep one side and you cut off the highs, sweep the other, you cut off lows. Nop, it's not the fender TBX but it is similar.

Re: Capacitors!!!!
The pair of caps between the volume pot output and the tone pot input perform exactly the same function as they would if positioned in circuit between one lug of the tone pot and ground. i.e. A passive low pass filter.
A pair of caps between lugs #2 and 3 of the tone pot itself would act as a bleed/bypass.
Combining the two ideas would result in a passive band pass filter, depending on the exact capacitance values chosen.

Re: Capacitors!!!!
2 capacitors in series reduce their value. The equation for total capacitance of series capacitors is the same as resistance or inductance in parallel.
(C1*c2)/(c1+c2)
Just an FYI don't think it's related to the question just a good thing to know

Re: Capacitors!!!!
I have tried a similar thing once - run a wire from the volume pot to the center lug of the tone pot and one .047uf cap from the right lug of the tone pot to ground and a .022uf cap from the left lug of the volume pot to ground. This will give you "two" tone controls in one knob, with the open setting somewhere in the middle of the rotation. This may also be the reason it is not used very often as the "full up" position is not easy to find, especially on stage in the middle of a song. That is why I removed it and never used it again since.
Caps in series is like resistors in parallel. The formula quoted above is correct.
