Slight crackle when turning CUTOFF button

Hello!

I’m the proud owner of two Mother 32’s and, recently, one of them started making a very subtle crackle noise whenever the CUTOFF button rotates and passes by the 200Hz line. This happens consistently, either when rotating clockwise or counter-clockwise.

Any ideias / suggestions / hints on the source of this or how can I try to fix it?

It’s not bothering me a lot, right now… but I can imagine it becoming an issue, especially if I start noticing it on my recordings…

Thanks!

For me this is a damaged potentiometer which should be replaced
