American company Seymour Duncan is well-known for its bass and guitar pickups, as well as its effects pedals. They are a true powerhouse in the guitar industry, and Seymour Duncan himself serves as their CEO. Founded in 1976, it didn't take long for these to be combined with the Floyd Rose trem system and found in Kramer guitars. From there, these pickups spread quickly to instruments made by Fender, Gibson, Yamaha, CHarvel, ESP, Ibanez, Jackson, Schecter, and a plethora of other manufacturers.
