The T-Type humbucker pickups are a nod to the T-Top pickups that Gibson made between 1966 – 1979. T-Type pickups use polysol wire and Alnico 5 magnets just like the original T-Tops, which are still some of the most popular pickups Gibson has ever made and a favorite of many of today's top players. The T-Type pickups have nickel covers and balanced coils, and like the originals, they are left unpotted for vintage-correct tone.
