Push/pull pot as a killswitch

    I have a MIM Precision Bass and would like to install a switch that mutes the signal to the output jack without changing its look. I figured using a push/pull pot as a mute switch (when in up position) would be a neat solution. Has anyone any experience with that or could help out with the wiring? I know there was a thread on this topic back in 2010 but the wiring diagram can´t be opened anymore. I´m quite new to this forum so bear with me, please.

    A kill switch is very simple to wire - when activated (pulled up in your case) the killswitch will connect the bass' output ('hot wire') to GROUND (earth). This mutes the bass signal and will be silent.

    If you wired the kill switch to simply disconnect the hot wire from the output jack, you'll get loud humming through your amplifier.

    I am not somewhere I can creat a drawing for you right now. Maybe @line6man can help with a description.

    But Welcome to TalkBass @LieutenantLauch !!!!!!!!

    Thanks to all of you. A drawing might help. I mean I know how to solder but other than that I´ve no idea what I´m doing in terms of wiring and electronics... :D
    If I got everything right, I just have to connect A to D (see attached drawing), the hot wire to B and C and the ground wire to E and F. Am I right?

    If you want to kill the signal when the knob is pushed in:
    signal wire to 2
    ground wire to 3

    If you want to kill the signal when the knob is pulled up:
    signal wire to 2
    ground wire to 1

    You'd need a momentary switch to do it so you can have this:

    I followed all of these steps closely and it works brilliantly. Again, thanks for your help. I gotta say, most forums I've been registered are full of wise guys and elitist douchebags. Here tho, I really feel like it's a just bunch of cool guys trying to help out each other.
  7. I've got one on my P and I absolutely love it. I'll probably install one on every bass I ever own from now on...

    Word of warning though, I pulled the shaft clean out of a couple of cheapo push-pull pots before I bought a decent quality one. (I forget the brand now).

    No issues since!
