Question about black bridge grounding - Simon and others have advised I scrape some of the black off - down to bare metal - for grounding. I assume that means scraping each saddle slot, and either the screw or the bottom of the saddle and in the trough where they slide. Also the bottom of the bridge at the post holes and the parts of the post the bridge rides on, and then the post and ferrule threads, and finally the outside of the ferrule body where the ground wire sits.
Did I miss anything, or am I overdoing it?
OR, should I just ground the trapeze tailpiece as the scrapes will be easier to hide?
