Hey, I'm thinking of setting up a high bypass on my volume pot. I use my volume for more then just volume, I also use it to adjust the amount of distortion when running at high gain. I like the idea of having my tone not change with volume level, but will this also hinder my ability to lower my distortion level using the volume pot? I was hoping someone here may have already tried this stuff out.
Im gonna use a Fender 680pF Cap and a 220K resistor, sound about right?
Thanks

On the original GNutz site, JA describes doing this with a .001µf cap and a 150K resistor. JohnH, a member here, has recommended the same cap with a 220K resistor. Not really a huge variation between the two. As far as whether it will hinder controlling the distortion as you describe, no personal experience on that but I suspect it would have an effect, might be a positive effect at that. You can always try it to see if you like, it's easy enough to take the RC filter back out if'n it doesn't light yer laser.

I think im just gonna try it without it, and if I really think I need it then I will add it. I will ask around the fender forums as well, see if they have tried it out. Thanks for the help

I just remembered where I got the info to use a Fender 680pF Cap and a 220K resistor. It was from the site www.acmeguitarworks.comHere is the link: www.acmeguitarworks.com/Strat_Assembly_With_Pickups_P148C132.cfmHere is the info at about the middle of the page: Volume KitWith a conventional guitar, when you roll off the volume control, some of the treble goes away. That is, in addition to the volume change, there is also a tonal change. Some people hate this, while other people don't perceive it as a problem in the slightest. If you are in the former camp, then this option is for you. It consists of a small resistor and capacitor wired in parallel across two lugs on the volume pot (see photo), with this in place the guitar's tone will remain consistent even when you roll off the volume. We use Fender's values for these components: 680pf capacitor / 220K resistor. I really don't know the difference it would make using their cap and resister verses the ones recommended on GuitarNuts. At least now I know where I got the info from.

The 680pF 220k is not much different to a 1nF 220k that I use. Neither affect the range of volumes that you can get, from 0 to max, at which extreme settings they have no effect.
The resistor has an affect of making the drop in volume as you roll away from 10 a bit less sudden, which I find to be good on a log pot.
Particularly if you use shorter cords, say 10' rather than 20', 680pF should be fine instead of 1nF, and probably a better value, but you may not hear much difference.

Ok cool, as long as they both work pretty much the same. I usually use less then 10 foot. I try to keep it as short as possible, I have a 20' but I only use it if I need it. Thanks for the explaination.
