Topic: Volume Pot worse after using Deoxit? |

I have a Goodrich stereo volume pedal. It's a dual pot, but that's probably irrelevant.
I started hearing a bit of scratching while using it, so I opened it up to Deoxit D5. I couldn't find any openings like I'm used to seeing on the back of pots so I sprayed around the base of the shaft and tried to work it in.
Now, it's far noisier to the point of being unusable. I cut the steel's volume completely off with it's volume pot and just rocking the Goodrich produces a loud scratching sound.
Any idea what happened or what I should do next?
The Goodrich has two inputs and two outputs and they both sound like this. |

| Pots wear out. Deoxit is a cleaner and solvent and can further erode the resistive surface if it is already wearing thin. A new pot is the fix. |

While you probably just need a new pot, you can try getting WAY more D5 in there, either by prying open or drilling the case, or by rigging up some sort of small cup to 'bathe' it in... I've maintained some vintage mixing consoles over the years and on the ones where a specific pot is no longer available and is of a style that doesn't lend itself to a convenient modern replacement, a mega dose of D5 could often keep a pot going for another couple years.
But just replace it though, there's good pots being made again

I drill a small hole in the case. 1/16 in. or so. Have to be careful not to go in too far.
Probably bending back the tabs and removing the case back is better...just make sure the notch is oriented the same as came off.
Carbon wears off as it rubs against the wiper and I suspect your attempt has moved some of it around inside.
If you pull off the case, you might be able to clean the loose debris out of there.
Might help, might not....but you got nothing to lose at this point. |

I had a scratchy AB pot in a steel I was working on recently. I pried off the cover and cleaned the pot with Deoxit D5, but it didn't eliminate the problem. I fixed it by bending the metal wiper assembly slightly so it contacted a different spot on the carbon track. I wouldn't recommend this except as a last-ditch effort, but it did the trick in this case.
All that said, I agree that the new pots are good and that's probably the best way to go. |

James,
I have the new pots, Dunlop, same as used by Goodrich, in stock.
These new pots have proven to be the most reliable on the market today.
I send a new string with every pot.
Let me know if I can be of service.
Regards,
Bill Ferguson

Spraying around the shaft gets almost nothing where you really need it, on the resistive element. If it has a cover, remove it, and spray the element and slider. Of course, if it’s the molded plastic body type, they’re pretty much unserviceable.

If you have a pot with metal clip on cover. Removing the cover and cleaning out any loose material. And spraying the rotator and contact, May cure problem. While cover is off. Drill a small hole in the cover and remove any inside burrs from drill hole. Spraying cleaner through hole may get you a little more use.
Replacing the pot is the only real cure. |

Thanks for all the tips. Here’s something strange. I tried it again today and the loud scratching is gone. It’s back to it’s previous state of subtle noise.
As it’s a doubled stereo pot, I wouldn’t be able to get both casings off and if I remove the pot to get off the bottom case only, I might as well replace it all because it looks like it could be a pain to install again.
I’m going to try to drill a hole later today. |

A shout out to Bill:
If you need to replace the pot James, Bill Ferguson is the answer. I am getting one from him. I had trouble in receiving his mail and making payment. 
Bill handled it in a business-like manner, and we have gotten things straightened out! 
Thanks Bill........Pat |

My VP has a double/stereo pot. Do you have one of those available?

A mono pot may be what's supposed to be used - the stereo pot was likely just what the last guy had on hand when he needed a new one - did the stereo pot get both gangs wired?
Maybe a photo would help out some

I don't know of a stereo pot.
If you have 2 pots in your stereo pedal, I would bet each one is a mono pot.

| one way to get cleaner down the pot shaft is to put a short piece of plastic hose over the threaded part of the pot,lay amp on its back ,pour cleaner in short tube.give it time to seep down in to the pot. |

It was definitely manufactured as a stereo pedal. You can do mono input to stereo output or two mono inputs to two stereo outputs.
