knob movement

[dirt lizard]

I keep finding myself moving back my discrimination knob back to it's original setting on my vaquero. Is there any way i can keep it from moving ?

A thicker rubber washer on the pot shaft may work

Put a 1/4" oring on the shaft and put the knob back on so that it puts slight tension on the pot when turning.

Before you try the O ring, loosen the set screw and move the knob down on the shaft.
You might have to adjust it up and down on the shaft to get the right resistance.
It worked for me.

Thanks for the help I'll try both and see which works better
