Ordered these for a budget build to trim out a pair of EMG pickups 81/85. They fit perfectly around the tight radius of the EMG. The trim rings are tapered and the neck ring is thinner than the bridge ring as others have pointed out, though the surface that meets the body of the guitar is flat, whereas Les Paul body styles would require a curved shape in the trim rings. The holes for the EMG's were spot on. I cannot account for the trim rings mounting holes as I was building a custom setup and had to mark and drill the holes in the pick guard. The mounting holes in the trim rings are very uniform however.
