Check for poor soldering. Also the jack or pots MAY be physically turning and shorting to the black shielding paint that is conductive in the "WELL" with the pots and jack. If you find that a lead is shorting to the paint, put some insulating material OR tighten to prevent rotation that brings the lead into contact with the paint.
