    On a JJ I replaced my EMG sigle coils with Nordy NJ4SE's (dual coil/humcancelling). It would seem to a neophyte in bass wiring (like me) that by their very nature, "hum-cancelling" pickups would not need shielding. SO, when pickups say "hum-cancelling" is that the same phenomena as the 60 cycle hum we are shielding against when we do all that copper shieldig in the pup/control cavities?
  2. There is no reason not to shield a bass.
    It's dead simple, just time consuming.

    Shield it anyways.

    NJ4SE are not dual coil. They are split coil.

    To answer your q, you are right no need to shield the pup cavity, but I recommend you do shield the ctrl cavity, still.

    I typically shield my bass from my kids....have you seen what a kid can do to a bass....?

    Yes, split coil (I knew that...). Thanks for the feedback guys.
