Modern Filtertron BridgeAn overwound bridge position Filtertron, based on the 50's originals, using 43awg formvar wire and oversized AlNiCo 5 magnets, it's wound to roughly 7. 4k to give you a bit more volume, bite and thickness, but still bright, clear, sparkly and articulate. Available with chrome cover, as direct body mount or humbucker mount (also known as "English" mount). Please note this is a direct drop in replacement for stock Filtertron pickups, not humbucker sized
