black bridge on DJB-4 Bass not conductive

[Trevor Davies]

So, installed my ground wire under my bridge and found surprisingly that the paint on the bridge is not conductive, and thus the ground wire is not grounding any of the strings.

Seems quite strange to me that I'm going to have to scrape off paint to get down to some actual metal that will allow me to ground this.

Anybody else run into this?

Yes. This is typical of all the black hardware - they definitely need to be filed, scratched or sanded to get a good connectivity with the ground wire. The black studs for the tuneomatic bridge or tailstop also need to be done!
