a good trick is to open up the electrics and plug the guitar in- so it's humming
Then with a length of insulated wire, touch one end of the wire to the jack plug body and touch the other end to every metal component
When you find the right component the humming will stop
If you've reversed the polarity on the jack socket - this will also cause a hum
A jack Plug is easy to wire, but a jack socket is not so visible and wires can get crossed
if you always take the lazy route
