No, I'm not going to re-contour the bridge. I'm restringing just the treble sections because of string breakage. Re-contouring means pulling the bridge pins and dealing with bridge cap, notching etc.? I've used emory cloth for the fine work but don't want to remove too much material so I figure on working along the sides, like hammer filing where you remove from the sides and light across the top...
