Confirming guitar grounding?

    I’ve been trying to figure out how to confirm if my guitar bridge is the ground in my circuit. I see the wires but I’m getting random buzzing intermittently. My bridge is chrome plated brass so it should be conductive enough. Is there a way I can use a multimeter to determine if the bridge plate is the ground

    Yes, use the continuity function and connect a lead to the ground on the output jack. Test the bridge and strings by touching it with the other test lead.

    >if my guitar bridge is the ground in my circuit<
    Or do you mean to say, IS it grounded?


    Well the bridge plate technically would not be "the ground", but connected to a ground point, that would have the connection to the jack wire. Usually, the back of a pot can is the common "ground all" point of contact.

    If the bridge/strings are to a GROUND POINT, any little hummmm,buzzzzzz you hear, SHOULD subside a tad when you touch the strings or bridge.

    If any noise increases when you touch the strings, that usually means the jack is wired backwards.

    If there is NO diff, when you touch the bridge/strings, then likely there is no or a bad contact (continuity) to the common ground point.

    Teles tend to buzz more in my experience.

    The strings won’t ground in my guitar because of my saddles but I had the issue before the saddle swap. I’m going to test with the multimeter in a bit. I appreciate the help!

    Some Graphtech saddles don't pass eletriciousness.

    The GraphTech TUSQ Saddles are a special plastic material that emulates bone but is also more slippery and has interesting frequency response characteristics. You can see the saddles on my guitar are an odd white color.

    I realize now that the saddles should not matter for the purpose of grounding. The strings still connect to the bridge baseplate via the string through holes and my hand typically rests on the bridge ash tray. I just have to get my multimeter out of my car...
