Pickup cavity shielding needed?

Discussion in 'Pickups & Electronics [BG]' started by tortoise.sg, Nov 14, 2005.

  1. I'm fixing up a warmoth jazz bass and just finished the control cavity shielding.. Is the pickup cavity shielding necessary?

    Just did it to my P - not completely done installing pots (waiting for my cloth wire to arrive) but initial tests prove that it's very effective for me. Of course the P and the J are different beasts. I have a USA J that's unshielded and is as quiet as can be.

    I just finished fully shielding my Yam. bb405 jazz 5 string that had bartolini jazz style dual coils pups (nj5...). The shielding in general helped a lot, but I did control and pup cavities all at once.

    May be a done deal already but regardless:

    Probably the most definitive answer to that question would come from putting it back together without shiedling it and finding out. May be fine or you may want to go back and reshield the cavity - and that may or may not make any difference either way.

    With everything torn up, there's rationale to shielding both and installing grounding plates to the pups as indicated. Everything's apart, all the materials are there - do it and be done with it and you don't have to remove strings and parts again.

    That's from a simplest practical point. From a technical point I don't know what the probability of a desireable outcome is from shielding one as opposed to shielding both. I've never ran across any material that said anything to the affect of shield both or neither cuase you're wasting time shielding one.

    Oh yeh, seems Sadowsky is a big proponent of shielding. So my guess is that if his pup cavities aren't shielded, he doesn't see it as significant for his basses.
