    There is a problem with a MIM Fender Jazz that I want to buy. When i turn the smallest knob up even a little, the notes are all scratchy. I have tried the bass on different amps and with different cords, same effect. It seems to be a problem with the cord connection, because if I turn the cord a little, the scratchy noise happens. Any ideas as to what the problem is? Is it fixable (cheaply)?
  2. sounds like an earthing problem.

    ps. its cord (or cable) not chord (a group of notes) and this is in the wrong section

    Sounds like an input jack problem. Oxidation over time can create a bad contact there.
    Get some 400 grit sandpaper. Roll it into a pencil shape, and put it in the jack where your cord would go. Swizzle it around a bit and pull it out and look at it. If it's all covered with rustly looking munge, roll another, and repeat.
    When done, clean the jack with a Q-tip doused with WD40, CAIG, or something. A bit of light work repated on your cables ends is good too.

    If none of this works, time for a new input jack.

    Thanks so much.

    Just in case, about how much would a new input jack cost? (MIM Jazz)
