Try this before replacing your scratchy wah wah pot

[@Moondian]

Weird approach, but it worked for me. Thank you.

[@orionsbassment]

Glad it helped

[@TheMrLoucrazy]

Yeah! Mine is like the same! Tks

Helpful, cool, subbed,

That BLACK STUFF is carbon. Carbon that dislodged from the trace. The trace is what creates the resistance track that the wiper rides on. I'll leave it to you whether the alcohol bath did that. There's a reason people buy aerosol products such as DeOXit and other contact cleaners... so you don't have to dismantle your pots or soak them in alcohol.

[@orionsbassment]

I have and love deoxit. I’ve found it doesn’t necessarily get all of the debris off the tracks. But generally speaking, this is this first order of business when the routine spray contact cleaners don’t fully address the problem.

Cleaning All The Worn Off Carbon Particles Off So They Aren't Getting Inbetween The (Pin 2) Wiper and Carbon Resistor (Pins 1 & 3) Will Temporarily Stop The Scratchy/Breakup.. But if The Resistor Path of The Potentiometer is Just Totally Worn Away By The Wiper By Long Term Use it's Just Going to Be Best to Replace The Old Pot With a New Replacement (But.. Make Sure to Get The Prpoer Potentiometer Value for Your Wah's Design/Rev, If You Don't Know The Potentiometers Value Set a DVM to it's 200k Ohm Range and Put The Probes on Pins 1 and 3 of The Pot and Note The Ohmage Reading)

[@orionsbassment]

All true. This is a temporary stop gap.

Should there be a smooth transition in the sweep from 1 ohm up to 100k+ ohms? Mine starts from 1 and steadily gets to around 11 then does a huge jump up to 3kohm, I can't seem to find anything about what the range of the sweep should be doing? Regards

@@al3633 Yeah.. That's a Big Jump (A Sure Sign of Carbon Wear) I'd Most Certainly Say That Potentiemeter Has Seen it's Day.

@@jfmax2000 thanks mate, ordered a new one, thought I'd try a cheap alibaba one first and see how it goes, cheers from down under

Cool, thanks, it worked perfectly for mine

Great to hear!
