I just bought a used Fender Powerstage 100 monitor. It's good and loud, but the pots are the worst I've ever felt. There is no nut attaching them to the chassis, they are just soldered to the circuit board and are so wobbly that I'm afraid to even pull the knob off the shaft so I can look inside. Short of replacing the pots, is there any way for me to get rid of the wobble? I've heard about Mesa using lots of hot glue, is this what they're doing with it, securing cheap components? Can I just dump a bunch of glue all around the bass of the pot?
