If you want to check you can bend back the tabs on the top and pull it all apart, to check for oxidation or other signs of electrical interference on the metal tape that surrounds the knob. I had the same issue, and if I'm remembering correctly, bending back the other terminal (the one you bent and soldered to the body of the pot) and attaching the lead there solved my problem.Īlso, could just be a dead pot. Not all pots are created equal, therefore not all terminals (right to left) will do the same thing.

Could be that you are attaching the lead to the wrong terminal.
