    Hey guys.

    Made a project bass from Fender parts and took the pickups from my -64 CS NOS Jazz Bass.

    Checked the wiring and soldering 1000 times but it keeps ending up like this.

    Neck pickup full bridge 0 - great sound
    Bridge pickup full neck zero - great sound.
    Both - hollow sound, less output and I think I hear a slight phase problem but I’m not sure.

    I’m completly stuck... and out of ideas?
    Has anyone had this problem?

    Can it be - Copper Shielding, old pots, bad wires?

    Help is unbelievably welcome.

    Best regards

    You can rule out phase if you swap the wires on one pickup.
    If it gets worse, it wasn't a phase issue.
    If it gets better, Voila!

    A slight volume drop with 2 pickups full is normal.
    A dramatic loss of volume and lack of los means out of phase.
