Title: Dumb guitar volume cap question
Post by: hamfist on May 23, 2008, 09:10:07 AM
I'm just starting to experiment with adding caps and resistors across the volume pots in my guitar to counteract treble loss when I turn the vol knob down.
   My question is ..... If I put a cap across the two non-grounded lugs of a volume pot, will it only affect the tone when the vol knob is turned down or will it also affect the tone when the vol is on 10 ?

It will only affect it when you wind the volume down, and by a larger amount as you get closer to 0.  You're allowing treble frequencies to bleed straight through to the output and essentially they're not using the volume pot.

Cool, thanks Dave. That is fitting in with my experience this morning as well.
  I seem to have got the right components in first time. I went for a 680pf cap and a 150K resistor in parallel across the the two ungrounded lugs of my bridge pickup vol pot. Apparently that is a fairly traditional combo. Anyway it does what I wanted it to perfectly.
