Trembucker (F-spaced) version of the legendary JB Model humbucker pickup from Jeff Beck signature series that has been designed in the early 70s and adds juice to the bridge position of any humbucker equipped instrument. Featuring hot coils, and alnico 5 bar magnet, this pickup delivers an unmistakable upper midrange attack, a tight, articulate low end, and harmonically rich highs that can really sing. It is the perfect bridge pickup for anything from blues & country to the meanest hard rock & metal. Trembuckers have wider pole piece spacing, perfect for symmetrical positioning under the strings of guitars with a tremolo or wide spaced hard tail bridge (2 or wider from the center of the Low E to High E directly over the bridge pickup). Pickup is hand built in Santa Barbara, uses an alnico 5 bar magnet, nickel silver bottom plate, 4-conductor lead wire for multiple wiring options, and is vacuum wax potted for squeal-free performance. Black finish.
