    Hey everyone, I'm new to the forum, so I hope I'm posting this in the right area.

    I'm having some problems with my Fender Jazz Bass. It cuts in and out, sometimes from full volume to a much lower one, sometimes just completely. Prior to cutting out it tends to break up a ton. At first, a quick heavy pick or strum and the distortion would subside, and everything'd work fine for a bit. Lately it's started getting to the point where it will start distorting or cutting out every time I played it. I took a look inside, but it looks like everything's fine. I am competent with a soldering iron, and have a good amount of experience with it, having replaced all the electronics on my Epiphone SG Bass on my own. I'd rather not have to replace all the pots and the output jack if its not gonna help anything.


    I've put some pictures of the innards up if that helps. Any help would be greatly appreciated! I'm sick of my SG and want my Fender back.

    @line6man is the person you wanna talk to. He's probably forgotten more about this than I'll ever know.

    possibly a dumb question, but have you checked your cable from your bass output? Or the output jack itself? i've had both problems before and both are easily fixable.

    Take it to your repair man.

    Sounds like some part of the electronics (probably the jack tip) touching the cavity wall which is painted with shielding paint. To test it try to play while the control plate is out of the cavity and see if it solves problem.

    This may sound crazy, but try cleaning the tip of the output jack...the little V shaped part at the end of the J-shaped part. Just use a pencil eraser to clean that gunk off. Otherwise, your wiring looks OK.

    Not a definitive answer, but your wiring appears correct in the pictures. if your cables, and amp are in good working order, my first step would be to leave the control panel opened, while plugged in, and wiggle wires, to try to find a bad one, I would do this by carefully moving one wire at a time, and not move others. Output jacks do go bad, simple as they are, my next thing would be to wiggle the cable, gently, to see if the jack is the culprit, if that's it, buy a Switchcraft # 11 jack, and replace it, (they are built a bit heavy, and are not prone to failure). the problem you describe sounds like a bad jack, or a bad wire, if that's the case, any movement would cause a problem. If I was working on it, my first guess (guessing isn't best), would be that it most likely isn't your pickups, though it could be a wire attached to them. If I was stumped, and couldn't figure it out, I would solder each pickup directly to a new output jack, along with the bridge ground wire, making sure everything was on the correct terminal, that would tell me if one of the pots, or a wire on the pots was bad, If everything worked great with the pickups straight to a new jack, I'd work backwards till I found the culprit. The reason I would spend 5 bucks on a jack..you can't always see if they are messed up between those fiberglass plates, from the cable plug moving around too much.
