volume pedal high freq rolloff

[grinder]

I am using a Boss FV50 volume pedal in my effects loop. It get me what I want as far as keeping my gain with the pedal rocked back @ minimum but it also rolls off the high end a bit. Anyone know of any way to combat this? I opened it up and it has a .0001 mF cap across. Any help would be appreciated.
Thanks, grinder

Across what does it have the cap?

If the cap is all that's in there besides a volume pot, thats obviously your problem...  :roll:

Hello Grinder,

The common way to reduce the cut of high frequencies when you turn the volume down is to install a small capacitor between the pot lugs that connect to the tip of the input and output jacks (not touching the ground lug).

0.0001uF (100pF) is a very small value for this capacitor (I'm assuming that is what that cap is for). Try raising the value to 470pF and see how that affects the sound. You might also want to try using 0.001uF (1000pF) in there. Play with the value until it has the sound you want.

I hope that helps.

Take care,
-Peter

Someting like this might go well in the cavity of a guitar...over a volumer pot or two...I read somewhere that if the 'right sized tiny' [a pf cap] cap is installed on the vol pot that a treble content boost with guitar volume rolloff can be had...

the jem guitars have a 330pf capacitor on them. some of the earlier models had a 470pf
