I have a Clarostat (I couldn’t find any Allen-Bradley) logarithmic pot that distorts only when there’s a signal thru it. I can run it from zero to full throttle without a scratch if I don’t pick any strings, but when I pick it scratches badly when I move the volume pedal. The pot is just a few months old and didn’t scratch at all when it was new.
I can’t remember any trouble like this with the AB pots I used earlier.
Any ideas what to do?

That pot needs cleaning, a solder joint is bad,a jack needs cleaning or the plug has a bad connection.
Try different cables to eliminate them from the picture.
Wiggle the plugs in the jacks to see if that will make noise. If that doesn't cause the noise, you can resolder the wires from the pot to the jacks and clean the pot (unless it is a sealed pot).
Sometimes new pots are scratchy until they get rotated a few times.

| Sometimes the pot is OK, but the moving pedal touches a wire and makes a noise. |

Thanks a lot for all advices!
Changing to a new pot fixed it. Surprisingly short life span of the previous one means time for a Hilton pedal, I guess, since good pots are history by now.

I thought that Hilton's pedal didn't color the sound at all. What's the Hilton owners experiences? Now I'm getting confused.
