As far as I remember Nolly was one of the first ones to have a Ceramic Nailbomb by request? I know for certain he helped to develop the Blackhawk as he had it in his Pink Daemoness Cimmerian even before the pickup was released, referring to it as "prototype" and as soon as it was out, only available with a ceramic magnet he posted a clip on his soundcloud with a special A5 version of the pickup, even offering DI's for download so people could judge by themselves. Soon after that the Blackhawk was made available with either ceramic or alnico magnets.
