Members ksl Posted February 19, 2022 Members Share Posted February 19, 2022 Greetings again,, just picked up this 70's Orlando MIJ guitar that someone who knows less than me, messed with.... If you check the underbelly, you'll see where the grounds for each p/u go to those screws that hold the switch in place... I've circled the corresponding points of contact on the top picture. I'm not getting any signs of buzzes or hum of any kind, except for when I move my hand close to either p/u, & the closer I get, the louder the hum... dynamo hum... Even with both p/u's switched off, I get this noise that I probably wouldn't get with typical playing, but something's not right, & should I run a wire from those 2 p/u grounds to the ground at the controls? Many thnx~ Quote Link to comment Share on other sites More sharing options...
Members badpenguin Posted February 19, 2022 Members Share Posted February 19, 2022 The grounding the way it sits should be fine. Might want to shield the inside of the pick guard and shield the cavity. Quote Link to comment Share on other sites More sharing options...

Grounding can be done many ways, as long as everything in the primary signal chain [pots/p-ups] is grounded to the bridge and the output jack, it should be fine. Shielding is a whole other matter...although it is related to grounding...and in fact must be grounded to be effective. Quote Link to comment Share on other sites More sharing options...
