Here's what Seymour Duncan say about the Custom 5 Trembucker
If the 59 Model Trembucker was twice as loud, it would be a Custom 5 Trembucker. Scooped mids, even bass & treble, and high output.
This is the Trembucker (F-spaced) version of the Custom 5 humbucker. Originally called the Custom Custom Custom this pickup began life in our custom shop from players requesting a brighter, alnico 5 version of the Custom Custom humbucker.
It has a nice, full tone, a scooped midrange, and strikes a nice balance of bass & treble. This even response makes it great for all types of music, great for both clean and dirty sounds, and great in all types of humbucker equipped guitars. Match with the 59 neck or Jazz neck model for a perfectly balanced setup.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).
Hand built in our Santa Barbara, CA factory, the Custom 5 Trembucker 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.
