Re: Beveled vs. unbeveled
Yes there is absolutely a difference. The original chamfer was done to aid bobbin assembly, so that the poles would find their way through the holes in the flatwork easily.
Sonically, the easiest way that I've ever heard it explained to me is that the bevel causes the magnetic field to shoot out a little around the bevel area, but that it results in a tapering of the field above that point. So if you could imagine the magnetic field shaped like the flame of a candle, or a teardrop for example, that should help you visualize it.
Too much bevel (like on Fender's Noiseless singles) and the field is distorted even more. Perhaps that's what they're going for, but we do the vintage Fender bevel. Seymour is very adamant about that vintage bevel. We take each one to the grinding wheel individually so they look a little random like Fender's did, but the actual bevel is uniform. It's pretty cool to watch them do it.
