When I installed my Fender 250k no-load tone pot I also installed the .022uf capacitor that came with it. Lug 1 of the no-load pot is connected to lug 3 (input) of the 500k volume pot, and the capacitor runs from lug 2 (wiper) of the tone pot through lug 1 (ground) of the volume pot and onto the case of the volume pot, which is connected to the sleeve of the output jack (also ground). Lug 3 of the tone pot is not connected to anything. The tone pot works exactly as it should, but there is occasionally a slight electrical "pop" sound when I turn the knob from 10 to 9, bringing the capacitor into the circuit. It doesn't happen every time, so my uneducated guess is that the capacitor is somehow building up a small charge when the tone control is disengaged, and then discharging it into the circuit via the volume pot's input when the tone control is engaged. Here are my questions: 1. Could I be correct about the source of the "pop"? 2. Is my capacitor faulty, or is this normal... or is there another explanation/potential remedy? Thank you very much for your help.
