    Can you tell if the white wire at the jack is connected to the ground/sleeve instead of the tip? It looks like the ground and hot (white) are backwards at the jack connections.

    (In electric guitars it's important that the ground connect to the sleeve of the jack (not the tip), and to the bridge, strings, etc. I purchased a used guitar that had the jack miswired like that. It would not quiet down until I opened it up and fixed it.)

    EDIT: It's hard to tell from your photo, but here's an image with the solder lugs labeled. Also, some of the solder joints don't look very good. You might want to touch them up with an iron and solder. If you have an ohmmeter or continuity tester you could check all the ground connections.

    If the sound changes just by moving the wire(s) then there is a bad solder joint on that wire. Or the wire is broken inside the insulation. Also, try pushing on the wires with something plastic or wooden (not metal, not your finger) and see if it still makes noise.

    Picture is a bit dark, but from what I can see:
    1) Jack is wired backwards ( as mentioned in post #2) i.e signal is going to the jack sleeve
    2) Most of the soldering is crappy (translate as very bad). Re-solder any/all crappy joins.

    Edit: Oh, and welcome.

    "I noticed when the amp is off, the line have electricity yet!!!!!"...

    do you mean that you feel electricity on the guitar? or there is power to the amp with the switch off? either indicates an amp problem which brings another question:

    have you tried the guitar through a different amp?

    with a different cord?

    I agree that the jack looks like it's wired backwards.
