When a pot is . . . NOT!
12/20/20 at 17:11:19
 
Both of the volume pots on my MT are scratchy, to the point that when I turn either one it is very noticeable, scratchy. I am wondering whether the pots are emitting noise occasionally at idle. Could these be cleaned? Or should they come out?

I had a scratchy pot on my CSP3.  By repeatedly turning it fully left and right -- full range, the scratchiness cleared up.  I'm guessing that some kind of oxidation happens on the contacts.

Thank you Arch for the suggestion. It seems to have removed the scratchiness from the pots . . . . for now.

I also have a scratchy pot on my mini torri. Mine are stepped(10 steps) Just noticed my Zbit has 20 steps, would like to replace the 10step for the 20step. Anyone know what these are?
Thanks
Joe
