    Hey! Yesterday I bought this bass guitar for really cheap (20€). The seller said it is from the 70's. I dont know anything about basses so please help me if you know anything about this guitar. I want to restore this guitar, there are some missing screws, one of the pots is not doing anything when turned, the other one adjusts the volume.
    Here are some pictures:

    My guess: a home built project. The neck doesn't look very original to me, and the body looks like it was made a bit sloppy. Pickups look Japanese.

    Thanks a lot! Do you think that the pots are wired correctly? The upper pot is the non-working one, what resistance value does it have? Can I buy one from an electronics shop and swap it with that?

  4. Take some closeup photos of the wiring & post them.

    Yes, you can buy pots to replace the current ones.

    You can check the value of the pots with a multimeter. (measure Ohms between terminal 1 & terminal 3):

    potentiometer-pinout.

    Those are humbuckers so the pots should likely both be standard 500Kohm audio taper.

    Thanks! Then I think I will buy one abnd test it. Could someone give me a wiring diagram because now it's really messy and I don't want to leave this way. Closeups:

    Why is the inside padded with tinfoil?

    It's pretty hard to see for me if the wiring is correct. I'd resolder everything to see if it works, and if it doesn't I'd suspect a pickup or pot is broken or something. Replacing pots might work :)

    There's tin foil in there to shield the electronics. Most people do that with copper foil but I guess tin foil might work too. It's supposed to reduce hum and interference from other electronics.
