Active bass output jack wiring

Discussion in 'Pickups & Electronics [BG]' started by canadian_man_44, Mar 5, 2014.


  1. So I decided to replace the output jack on my precision deluxe active bass due to it being very loose on the cord and causing sound issues. Took the old jack out and started to out the new jack in and realized that it only has two connections where the old one had three. The bass has black, white and blue wires. Can I use this output jack and if so, where do I connect the wires?

    Life lesson: take "before" pics.

  4. That was damn helpful. Thanks.

    If the jacks had been the same it wouldn't have been a problem.
     
  5. Looking at a wiring diagram would be damn helpful.

    You need a TRS jack with active bass because contact with the ring acts like an 'on' switch. So no, you can't use that jack. Hopefully you can use the appropriate diagram to put it back together without pulling the pickguard off, but I don't know how uniform the wire colours will be between different runs. Output to tip, power to ring, ground to sleeve.

    An active basses uses a trs (stereo) output jack to act as a 'switch' to apply power to your preamp when you plug a cable in to the bass. You really need a trs jack to do this properly. Otherwise, if you rewire it to work with the ts jack you have, you'll be constantly draining the battery for your preamp!
     
  7. TRS jack it is then. Thank you. I still have the old jack with short parts of the colored wires attached so rewiring with the correct jack in hand won't be an issue.
     
  8. The output from the preamp should be wired to the tip. The battery negative wire should go to the ring. The cavity ground should go to the sleeve.

    Good luck.
     
  9. I also found the full wiring schematic for my bass. :)

    you probably could have still used the old jack. it might have become loose because the tip was bent too far out from usage. pushing it back toward the center would have fixed that. then cleaning it up with alcohol for the dirt and grime that accumulated
     
  11. Yeah I tried that and it didn't help much. Got a new jack yesterday and I'm wiring it up tonight.
