A few of my potentiometers are scratchy on key audio modules, eg mixer and att. This is less a problem with cv or freq, but when it’s going directly to audio out it quickly becomes a problem. No one wants scratchy volume control.
Does anyone have any tips on how to solve this issue besides replacing the pot?
As an aside, in my opinion I think higher quality pots should be used in audio specific modules in the future (if available).

There are contact cleaner sprays which are also used for electric guitar pots. If that doesn’t help and the pots are broken, they can also be replaced. Desoldering them shouldn’t be hard on the AE modules, but of course that’s a DIY task for a rainy Sunday and a last resort effort.

Thanks! I'll look into those guitar sprays!

Caig Labs DeOxit D5, baybee!!! You think scratchy pots are bad? Try freeing up and reviving slider pots that've been FROZEN due to disuse and crud! DeOxit is THAT STUFF!
It's simply effing amazing, and I've been using it since my old Nashville days...where ALL the engineers keep a can or two handy at all times. Bad noise? Spritz a little and exercise...and voila!
The only thing it doesn't work on is food. For that, God invented mayonnaise. But don't trying using THAT to clean controls...  |

I second that (and most other fluorocarbons in a can for circuits and pots). I am about to go way chemical on the pots in a 1986 Ibanez RoadstarII 5-string bass that I recently found lying on the street in the rain. It looks like it's been under the sea for a while but the neck is still straight (thank you un-named 1980s luthier in the Takeda factory near Nagoya) so anything else, I can get working.  |

Yeah, Caig has a whole line of these substances, all of which are DA BOMB. You might actually need something a bit more drastic than D5, though, so check 'em out: caig.com/
They also just came out with a line of DeOxit greases specifically for control lubrication. Pack some of that in those Ibanez pots, and you should be able to play that bass in the shower! And no, I don't get a dime from them, but when something is this good, this consistent over decades (literally!), and this reliable...you want to tell people!

The volume knob on my HPAMP module is super noisy too. Will this magic substance fix that? Sounds different to an old scratchy slider, something's not quite right

Right...it takes more time than the AE's been around for a pot to get THAT filthy. Sounds more like a defective component...which isn't all that surprising when you're going thru pots like they're potato chips.  |

Hello there,
I've got the same on a few modules the worst on MultiFX Wet and Dry.
I did try twiddling them for some time, that's worked on some others.
I have in the past with larger pots use WD40 to great effect.
I'm a bit apprehensive about using it on these ultra small pots though.
Has anyone else used it successfully?
Cheers

Not sure WD40 is ideal for spraying into electronics - you might want a dedicated electrical contact cleaner spray. There is a specific type of WD40 for electronics which I've used (not on AE I don't think, but don't see why it wouldn't work)

Servisol or deoxit is probably a better choice than WD.

Hello dizzeesatchel and Hello tIBThanks for the advice some of the stuff was so expensive here in the UK like £28 + £12 postage! But then I found this on eBay
I'll try a bit where the shaft meets the body of it under the front panel can't see any other way of getting at it. I'll let you know what happens. Cheers |

I run DEOXIT, the green stuff that has the lubrication in it. The red stuff is just for cleaning; it will strip all the lube off. However, the green stuff works wonders for me.

I've used serivsol to clean pots/sliders in the UK, wasn't very expensive from memory - Got it at a proper hardware store/Ironmongers! (i.e. not one of the big sheds like B&Q).
