    Hi folks,

    Nordstrand nj5st pups
    Aguilar OBP-3 pre

    It was suggested to me that I should solder the hot wires of the Nordstrands to their respective volume pots, and to solder the ground to the backs of their respective volume pots. Is this the best way to ground? Are there other options? Thanks!

    Wow, that one's pretty complex. I'll have to reread it a few times to get the jist...

    Easy to sum it up:

    • use copper foil to completely shield the control cavity
    • solder the sides to the botton, and check with an ohm meter to make sure it's all grounded
    • cover the control cavity cover with copper foil
    • the hot leads go to the blend pot terminals
    • you do not need to solder a ground lead to the pot body
    • the ground leads are connected to a star washer, and this washer has a ground lead screwed to the cavity side
    • the pots are grounded because they are in contact with the grounded copper shielding

    It's a lot easier than it looks at first. If you follow the process, you'll have a dead quiet set-up.

    All the best,
