    Hi All

    I've dusted off my Bass Rig after a few years on the shelf.

    Ampeg B2R into Hartke 410 & 115.

    Got a major ground hum whenever I'm not touching the strings.
    Also disappears when I place hands on the Ampeg Head or the jack.

    Can I rule out the instrument???
    Major hum disappears when I touch the strings on my 70s P. It's fine in a mates practice amp.
    My electrice guitar is also humming when plugged in, and hum disappears when I touch the strings.

    Input jack is a little scratchy at times - ie squeeks and squarks if I twist the cable.

    I've used different instrument leads - the same issues regardless of lead.

    Scratchy jack a good starting place?
    SHould I try a different power cable?
    Speaker Cables?

    All advice appreciated.
