Like a good soldier I searched the forums before posting this, but didn't find an answer. I just installed a used Badass II bridge on the Bastard Beater. Set the string height and intonation, but now have a loud ground-like hum. I removed the BAII, looked under it and the rear Jbass copy (Essex) pup ground wire is in the right place. Should I grind some of the chrome from the bottom of the bridge to facilitate a better ground? Or what else could be wrong? The stock bridge didn't hum like the BAII. Thnx!
