Rickenbacher B6 grounding

Post by Eric Dahlhoff »

Happy Holidays!

I've got a B6 "Panda" with celluloid white plates. I'm assuming war-time build. Really fun to play. 8)
But... in some circumstances I get the typical single-coil pickup buzz, unless I touch the pickup or jack, etc.

How do people ground the strings on these?

Thanks

Some folks fabricate a thin metal shim to put on ... Between the ball end and the loading Bakelite area ... Then run a wire from that to the sleeve of the 1/4" jack ...

I've seen other folks weave a thin gauge wire around the strings between the bridge and the body and run it to the jack.

A simple option is to get one of those static electricity bracelets for working on sensitive electronics ... put it on and run it to the jack ... I do this on my prewar bakelites in winter sometimes ... when it's really dry and staticky.

Hope that helps ...

Thanks Tim, but mine has plastic plates not metal.

Thanks for the ideas Rick. I think I'll try a piece of copper tape behind the bridge and a wire to the pickup mount. I do like the idea of the anti-static wrist band :idea: :!:

This is how I did it. I didn't want to do any further mods to this guitar, so a simple wire to the bridge.

The bridge must be grounded to reduce the hum. Any way you can get from the bridge to another ground point should work. Make sure you have a solid connection.

That's the issue with prewar and "wartime" Bakelites ... the bridge is integrated bakelite ...

Looks versus functionality. The way Mike Neer did it will work just fine. If you can find a more elegant way, go for it. If the bridge isn't grounded, the strings act like an antenna, picking up any spurious noise floating around.

I worked on a mid 70's Fender P Bass once. Original owner for 20 years was having serious hum issues. Multi meter showed the bridge was not grounded. The ground wire came up through a hole in the body and was merely laying under the bridge plate. Over time the wire had depressed into the wood and oxidized just enough to lose the ground. I soldered a star washer to the wire, made sure a screw went through the washer. 20 years later, still works great. If you want to reduce the hum, you have to ground the bridge.

Read the post over again. Are the saddles for the strings bakelite? If that's the case your kind of stuck. I am an electronics tech, but have no experience with these old guitars.

Yes, the saddle/bridge is all part of the bakelite body. Not a spec of metal there!

See if this doesn't make sense:

Stephen, that's perfect! Much better than my idea of copper tape.
I love this forum! :idea: :idea: :idea:
Thanks!

The paper clip is a great idea too!
Here's what I did. It has the advantage of grounding all the strings.

Great job Eric... glad to be of service! Couldn't have done it better myself.
