On the birdge pikcup, it seems obvious enough. Put a thin metal flat on top of the normal thick, curved bottom ring. But on the neck pickup, I'm not sure there's enough room there to put something on top of the existing ring. Would I need to just replace the ring with a metal one, thus losing the dual-tone look for that pup or do you think I could fit a flat on top? I'm nervous to order the parts until I'm fairly sure they'll work.
