Humbuckers and Trembuckers are very similar to each other, and most humbucker models also come in Trembucker versions. The Trembucker-spaced JB, for example, is a TB-4 and the humbucker-spaced version in an SH-4. The only difference is the wider spacing of the pole pieces on the Trembucker versions. Trembuckers are designed for wider string most commonly associated with Floyd Rose or vintage Tremolos with a string spacing of 2.070" or 52.6mm, measured center of high string to center of low string over the bridge pickup. Humbuckers are designed for bridges with traditional Gibson humbucker string spacing of 1.930" or 49mm.


Seymour Duncan Blackouts are a line of active pickups. They are known for their harmonically rich, deep sound and high output. In addition to the standard AHB-1 model, there are the more aggressive, higher output AHB-2 Blackout "Metals," which feature increased treble and mid range, and the AHB-3 Mick Thompson EMTY pickups, which have increased bass and treble, as well as higher output, although not as high as the Metals.
