The Fender noiseless pickups were designed by, and for a while at least.. made by... Bill Lawrence (the real Bill). I'm assuming only initial production was by BL and soon thereafter made by Fender in their own plant, also initially supervised by Bill himself (or so he's said).
Bill has a very good reputation for making clear bright pickups. Having said that, I thought the Fender noiseless were a bit too thin for my taste, but... I'm sort of a fat wound single coil sort of player anyway, so what do I know.
