All, I bought a body, neck, electronics and am in the process of building my first bass. Just so you know, there is currently no route under my bridge for a ground wire. For now, this bass is going to be a passive P/J config (Dimarzio P/J pups). I've wired everything up with the grounding in series as instructed by the wiring diagram that comes with the pups but do not have it grounding to the bridge. I cannot test it yet as I ordered the wrong 1/4" jack (waiting for the correct one to come now) and I also have yet to mount the neck and the body is going out today for refinshing. So currently the pups are just wired to the pots on the pickup guard. Anyway, should I made a route to the bridge? I'm just a guy with regular tools. I can drill a long hole from the rear strap button that travels under the bridge and into the rear pup cavity. I can then drill a hole down from under the bridge into that hole and route the ground wire from the pup cavity to the bridge. So do I need to do this? Are all basses grounded at the bridge or can they just be grounded thru the input jack and ultimately thru the grounding within the amp?
