    I already know how to do this task, but my question is based on having already shielded the cavity of the bass. But this is where I am, the pickups are sealed nicely in epoxy with one good coated wire covering 4 conductor wires for hookup. Do I really need to ground the two pickup cavitys together since the pickups are sealed in epoxy?

    EMI doesn't care about epoxy. The shielding is there to stop the EMI from getting to the pickup & it can't do its job if it's not grounded.
    They don't need to be grounded to each other, but they do need to be grounded to the controls cavity, which essentially does electrically connect them both.
    Axstar and mech like this.

    Grounding is only as good as it’s weakest link. If something is not grounded it’s a potential source of noise. Kinda be like insulating your entire house but leaving the front door wide open.
