Volume knob and LP filter changing by themselves without touch

[randomknobs]

Hello, especially concerned with LP changing by itself.
Have a gig next week, working on a set, and now this)
Looks like it happens with knobs which has mettalic pots, also noticed there is a threshold around 140...if i go below it it gradually starts to go to 0.
Any hacks?

Thanks in advance)
