Members Rock_and_roll Posted July 17, 2009 Members Share Posted July 17, 2009 its a tobias 5 string with active pickups, and i've noticed that theres a wire loose inside, its the thick white wire shown in this pic http://s117.photobucket.com/albums/o65/Rock_and_Roll_photos/?action=view¤t=IMG_2625.jpg the bass still outputs sound fine as far as i can tell, and i can't see anywhere obviously missing a wire, anyone have any ideas?

Members solderjunkie Posted July 17, 2009 Members Share Posted July 17, 2009 It looks like the ground for the bridge. Most "active" electronics prefer to leave the bridge ungrounded. Link to comment Share on other sites More sharing options...
Members Rock_and_roll Posted July 17, 2009 Author Members Share Posted July 17, 2009 thanks, yeah looking a bit closer at the end of the wire it doesn't look like it's ever been attached to anything so that explains it Link to comment Share on other sites More sharing options...
Members lUserName Posted July 17, 2009 Members Share Posted July 17, 2009 never understood why they make you remove the control cavity cover to change the battery...lame. Link to comment Share on other sites More sharing options...

Nothing harder than attaching one of those. Actually I didn't know that they don't connect a ground on active basses, are you sure about this? Do you notice any buzzing that would go away when you touch the back of a pot? if so, I would solder it to one. Link to comment Share on other sites More sharing options...

Most active basses are not as susceptible to EMF noise, so the player can be un-grounded. A properly-shielded passive bass can live without a bridge-ground too.

Members JovialEvil Posted July 18, 2009 Members Share Posted July 18, 2009 I have a question about the bridge ground. I am assembling my bass pretty soon so I have to run a ground wire underneath the PG or drill a hole to the bridge? Link to comment Share on other sites More sharing options...
Members knuckle_head Posted July 18, 2009 Members Share Posted July 18, 2009 Some use a strip of self-adhesive copper shielding from under the bridge to the nearest pickup cavity - you'll see it but it'll do the trick. Link to comment Share on other sites More sharing options...

I am assembling my bass pretty soon so I have to run a ground wire underneath the PG or drill a hole to the bridge? I wouldn't use a passive bass without one, it will have a buzz that will ruin the tone. The body you have must already have a hole in the side of the control cavity where a bridge ground wire once ran. You should see if you can run a wire through it, hopefully it will come out somewhere near where you are going to mount your new bridge. You really don't have to solder this end as long as the bridge gets screwed down tight on top of the wire (you can flatten the wire if you use braided), strip the insulation and place it under your bridge so it contacts the bridge then solder the other end to the bottom of the volume pot.

Ha Ha.. I just looked again and found a hole. I have never seen it before, it must be it. Took a little bit of drilling by hand w/ a small bit in plugged holes but I found it.
