What is star grounding? Why is it important?
A. Each component should have only one ground connection, all wired to a common point. This is called star grounding. Multiple paths to ground create “ground loops,” minuscule voltage differences between components. Hum “rides” the voltage differences, just like a humbucker pickup in reverse. John Atchley’s Guitarnuts website site has an excellent guide to proper wiring and shielding.
