Seymour Duncan TB-4 JB Trembucker Reverse Zebra Pickup

The TB-4 JB Trembucker delivers aggressive, articulate bridge-position tone with a tight low end and cutting midrange character. Built with Alnico 5 magnets and hand-crafted in Santa Barbara, this pickup excels in high-gain applications while maintaining clarity across all frequencies. The reverse zebra coil configuration provides visual contrast and refined voice for players demanding maximum output and definition.

Tone & Output

At approximately 17.64k DC resistance, this pickup generates substantial output ideal for heavy genres and overdriven amplifiers without sacrificing articulation. The Alnico 5 bar magnet and vacuum wax potted construction ensure consistent, noise-free performance with tight magnetic coupling and enhanced sustain.

Design & Wiring

The trembucker spacing accommodates guitars with string spacing greater than 2.00" (E to E) at the bridge, aligning magnets precisely with wider-spaced strings. A 4-conductor lead wire with approximately 11" of cable length enables series, parallel, and split-coil wiring configurations for tonal flexibility, and includes a four-conductor hookup cable for straightforward installation.
