Volume control fix

[dirt lizard]

Can anybody tell me what size allen wrench goes to the knob screws? It feels like the whole piece is turning when I turn on the volume control knob and my control is off set. I'm not sure if the nut on the volume needs tightening. Thanks

Really small for sure...your local hardware store will have one..just take your unit in to be sure....

I found the allen wrench to fix the problem. The nut behind the knob was very loose so I tightened it and all is well now.
