The HB-102 was modeled after Seymour's favorite humbucker combination, the USA-made SH-4 JB™ bridge and SH-2n Jazz Model™ neck set. Like the HB-101s, these pickups also use Alnico 5 magnets, but have a hotter winding spec, based on the world's most popular "hot-rodded" humbucker. The bridge pickup is Trembucker-spaced.
