Grounding wire: ground is ground is ground, right?

I'm working on ironing out the kinks in a Silvertone 1454, a very cool triple-pickup single cutaway bolt-neck hollowbody from the early '60s. Whoever monkeyed around with this one before me disconnected the bridge ground wire. The guitar is wired with the individual vol/tone knobs BEFORE the individual on/off switches, so I can't solder the new ground wire to the back of one of the pots without losing the ground when all three pickups are off. Plus, the holes under the pickups are not much bigger than two postage stamps (they're surface-mounts for all practical purposes, the hole is really just for the wiring). Besides, just thinking about fishing six mini-pots in and out of an f-hole makes my liquor bill go up. Where's the best place to tie the ground wire in this case? Any reason I can't tie the bridge ground wire to ground at the jack? Fishing the jack in and out will probably be easiest on this guitar anyhow.

Here's a guitar just like the one I'm working on, in case you're curious.

Yeah, ground is ground. But I'd sure try and ground the bridge or you'll get noise when you don't have contact with the strings/bridge/guitar.

I'm a bit confused. Do the switches in these also switch the ground? I'd have thought the grounds on the pots would be connected, no matter whether a switch was on or not. Either way, you should be just fine with grounding at the jack, I'd think.

That's what I would have thought. Since I've never fished all of the wiring out, I can't speak to exactly how it's wired in there. I can get a grounding effect touching the cover of any of the pickups, unless all of the switches are off, in which case it buzzes as if as if there's no ground. That must mean that the switches are breaking the covers' connection to ground somehow. I think.

From the Bigsby to the jack. That'll either work or cause it to burst into flames.

Interesting! I agree; just wire it to the jack and see what happens. Good luck if it's the "burst into flames" option! Laughing

Well, you've got consensus, but I'll chime in anyway. It's fairly - fairly - safe to assume the ground on the jack runs to the pots, so that's the reasonable place to attach a bridge ground.

But you know guitar players - they're always trying to be creative! (hope you don't find too much creativity in the wires.)

Reporting back - running a ground wire from the Bigsby to the ground at the jack worked great. Did a gig with it last week, and it's as good as I remember it being before it went out on 'injured reserve' 10 years ago!
