guitar wiring ground connection
Ground wiring on the guitar should ensure that the pick-up body, pick-up common, commons / bodies of potentiometers and the ground wire for the bridge get terminated at the 'common' terminal of the output jack.
Grounding would be automatic through the guitar output cable sheath, amplifier input jack 'common' and chassis ground.
Soldering would ensure reliable connections, obviating the need for a strip with screw connectors.
