Wobbly knob

  • Greetings to those infected,

    I have a Virus B which I've owned for about 2 years and it's value knob starting getting a little wobbly. It still turns, value changes, but it doesn't have the snug turn as the other knobs. I took it off, cleaned it with a q tip, even replaced it with another knob on the synth, but it appears the problem is with the actual prong. Is there anything I can do?
