Seymour Duncan TB-4 JB Trembucker White Pickup

The TB-4 JB Trembucker delivers a punchy, articulate response with tight low-end definition and aggressive midrange clarity. Designed specifically for tremolo-equipped guitars, this pickup excels in high-gain applications while maintaining note separation and dynamic range. Hand-built in Santa Barbara, this is a workhorse bridge position pickup for players who demand clarity without sacrifice.

Tone & Performance

The Alnico 5 magnet combined with a nickel silver bottom plate produces a bright, snappy character with pronounced midrange presence. A resonant peak of 5.5 kHz and EQ voicing of 5 bass / 6 mid / 8 treble deliver cutting articulation ideal for lead work and heavy rhythm playing across a wide range of genres.

Design & Construction

F-spaced pole pieces accommodate the wider string spacing on tremolo-equipped guitars for even magnetic response across all six strings. Vacuum wax potting eliminates squeal and microphonic noise, ensuring stable performance during high-volume sessions and extended sustain.
