Varitone wiring help - need to eliminate static electric "pops"

    I wired myself up a varitone/decade switch using a rotary switch and five different capacitors which all connect together to ground. It works as I expected it to except that I get "pop" sounds when I first turn the switch to each position after plugging in the bass. After I turn through all the positions the pops are gone until I plug it in again next time.

    Can I use resistors to eliminate these static electric pops? If so, how would I wire them in?

    A 1 megohm or greater resistor soldered in parallel with each capacitor should fix it. Wattage rating doesn't matter here, use the smallest resistors you can find.

    Thanks!! Connect one of these to the end of each capacitor lead and then tie the resistor ends together to ground, right?
