Billy took two magnets out of a box and handed them to me and said, “Try and pull these apart”. They were the strongest magnets that I’d ever felt. [...]
Then Billy opened a case that had a thin hollow body Framus with two of his new pickups mounted. The tops were made of brushed flat stainless steel and the coils were glued directly to the plate — no sides, no base. He plugged the guitar into a transistor amp with a JBL speaker and proceeded to demo the pickups and his coil switching circuit. [...] The magnet demo was great, and his series/parallel coil switching was an innovation.
