Seymour Duncan TB-4 JB Trembucker Black Pickup

Seymour Duncan TB-4 JB Trembucker Black Pickup

The TB-4 JB Trembucker is engineered for bridge position aggression on tremolo-equipped guitars, delivering the high-output punch and articulation needed to cut through live mixes and studio sessions alike. Hand-built with Alnico 5 magnets, this pickup maintains string-to-string clarity under hard picking and high-gain settings, making it a dependable choice for gigging musicians playing hard rock, metal, and alternative styles who need a pickup that stays tight and defined night after night.

Tone & Output

Rated at 16.6k Ohm DC resistance with output in the 17.4K ohm range, the TB-4 JB generates aggressive midrange punch without losing articulation across the neck. The Alnico 5 magnet responds dynamically to pick attack while delivering natural sustain that holds up in both clean tones and saturated gain—essential for players who move between dynamics and distortion on stage.

Design & Build

Built with Trembucker spacing to match tremolo bridge geometry, this pickup maintains balanced magnetic field alignment across all six strings without hot spots or dead zones. The nickel silver bottom plate and potted construction eliminate microphonic feedback and hum, critical for reliable live performance. Four-conductor lead wire opens up series, parallel, and split-coil wiring options, giving you sonic flexibility without rewiring hassles.
