Author Topic: Volume cap/treble bleed ... how to ? (Read 3694 times)

Anyone know which parts to solder in what way in order to obtain the effect that treble is retained when turning down the volume on guitars?

I think this is a combination of resistor and cap in parallel?

It would be important that sound is unaffected when the pot is on full?

Different parts for humbucker and single coil guitars I suppose?

Where the web is full of info about tone capacitors, there is hardly any real info on volume caps.

Any info would be great!

gordon smiths are treble bleed circuit, if so have a wiring diagram

If you want a treble bleed cap so that it stays bright sounding as you turn down (fitted between lugs 2 & 3 of the volume pot)
Also recommend a 150K resistor in parallel with the cap
I posted a piccy of this in a previous post- repeated below

Thinking of doing this myself, so lugs 2 and 3 are middle and earth then? How about values of cap and resistor? What's a basic rule of thumb?

No - 2 and 3 are the other 2 lugs where the input from the switch or pickup goes and where the output wire goes..

You are kind of letting some high frequencies bypass the pot and this gives a treble bleed/bypass

I just installed a treble bleed mod on my Gretsch. I must say it works. The treble stays in bu there's a down side: The vloume won't roll off as graduately as it used to. When I turn the volume knob down, the difference in volume is minimal untill it cuts out completely.

I think I'll remove it again.
