    Hello fellow talkbassers! I have a question that I know someone here can help me with.
    Here goes. I'm going to be installing new Seymour Duncan passive pickups in my Schecter Session bass. It now has active pickups so I have to replace the pots with 500k pots. I'm going to wire it stacked vol/vol and a push pull tone pot so I can have two tone cap. values. I could not a cts stacked pot with treading long enough to go through body so I ordered a mini pot from allparts.

    Problem is I'm not sure where to ground the two lugs as the pot back isn't solid and there's a lot of plastic right under the back so I'm considering finding a solder lug and soldering to that but any help would be wonderful. Thanks to all.

    You can solder anywhere on the body - maybe the sides. Or don't solder the pot at all and use a Lockwasher lug between the pot and the body and solder to that:

    But if your cavity is well shielded and grounded, you don't need a ground wire on the body of the pot at all.

    Thanks. That what I meant by solder lug. I figured I could run the ground from the lugs to that. My cavity has the shielding paint but I'm thinking I will shield the cavity with copper shielding. I also thought about making a common ground for the pick up ground wires with a lug grounded to the shielding and the tone and volume ground to a common ground on the jack.

    You can introduce noise by putting copper sheeting over grounding paint. I don't recommend it. Is there a problem with the shielding paint?
     
  5. Yeah, don't put copper over shielding paint. If the existing shielding paint has been applied too thinly to have good conductivity, then add a few layers of new paint, on top of it.

    No there's nothing wrong with the paint. thats what I saw in other forums on other sites that claimed that was the way to go. That's why I come here before doing anything.

    I did see on this site where another player covered his cavity in copper shielding and then put a lug onto the cavity side and put his pickup ground wires there. Can I do that then put the ground wires from the pot lugs to a washer lug between the pot and cavity.
