What's the cap value to keep a pickup consistant thru the whole guitar vol range??

[SQUAREHEAD]

Help!!!
When I adjust my guitar volume down a touch, the pickups go dead, blunt, awful! There is a cap I can install for each pickup?? Or just at the pot??
I used to know...
Old age is tough!!

Humbuckers or single coils and what pot values?

Oh! Sorry!
Two humbuckers, one volume pot-500k, no tone pot.

Most people use just a .001 mf cap across the two non-ground lugs. I like the Kinman mod (.001 mf cap in series with 130k resistor) better.

Thank you Zhangli!!
Ok... Where do I solder the .001 mf cap in series with 130k resistor in?
Do I need to do this for BOTH pickups or can I just do it to the volume pot?

Thanx

Just on the volume pot! Nowhere on the pickups! Solder the cap and resistor together, then one end each of this combo to the two lugs that are not soldered to the body of the pot.

John Suhr uses 150K in parallel with 680pF and Fender, 330K with 560pF. It's up to you !

There's different ways to go about it, and some say you have to vary the Kinman mod for 500k pots, doubling the resistor value and cutting the cap value in half. I haven't tried that so I can't say.

Thanx Guys!!
I can pull apart an old Marshall, bias it and the rest, but guitars are
not my thing at all!

Okay geeks, here's my hi pass mod. Take the cap (or cap/resistor couple) from the center lug of the volume to the right lug of the tone control. Tap the right lug of the volume control (or the switch lead) to feed the tone pot. This way, you have the hi pass filter on the volume knob, but it intuitively is taken out of the equation as the tone knob is turned down.

My biggest complaint with the hi-pass filter (resistor buffered or not) is that if you like to play with the tone control, then when the volume is down with it you are cutting highs and lows. Because hi pass is low cut. So say the tone is @ 0-3 for jazzy tones. Turning the volume down cuts the lows, leaving the mids and highs entact, essentially "midranging" your sound.

This mod makes a totally intuitive relationship between the volume and tone. It doesn't require ANY player awareness, either. Just play it normally, and it's an improvement all around.

If you've got a hi pass filter in a guitar already, it's so easy to try. Just remove the cap from the right lug of the volume pot and jump it to the open lug on the tone pot.

Thanx Bro!!
I don't have a tone pot in this guitar, but I can see the reasoning behind what you're saying!!
