Okay my friend has a Warlock and recently the volume knob came loose. We opened up the back and saw one of the wires was loose. Both me and him were wondering if he should fix it himself with a soldering iron seeing how we both have basic soldering experience or if he should take it to a shop.
Obviously Fassa.

Do it yourself. It's easy. If you can't be bothered to look up a wiring diagram, just find a glob of solder on one of the volume control's pins that doesn't have a wire attached to it.

If not, look up a diagram on a pickup manufacturers website. The colour coding might not be the same, but the wiring is. You'll be able to tell which wire it is that broke.

Where does the wire lead to?
