I recently picked up a used G&L bridge in the classifieds for a future parts bass build and I was surprised to discover that it is not as similar to a Fender bridge as I expected. I had owned an SB-2 years ago, but since I never removed the bridge, I had no idea that the underside of a G&L bridge plate has a 1/4" oval shaped protuberance hanging off of it. Since I will probably be slapping the bridge on a used MIM or Squier body, I don't have any concerns about routing a relief for the extra metal, but I am left wondering what the purpose is for this. Does anyone know why this was added to the bottom of the bridge? Because my background involves more metal fabrication than woodworking, my first instinct was to grind the whole thing off and create a level bottom to the plate. Routers are probably my least favorite power tool out there. My other observation is that this bridge probably weighs about a pound by itself.
