Seymour Duncan TB‑4 Trembucker, (Used)

The Seymour Duncan TB‑4 Trembucker is a high‑output humbucking pickup designed primarily for the bridge position of Stratocaster‑style electric guitars. It replaces the traditional single‑coil bridge pickup with a dual‑coil design built to fit in a Strat routed for a single‑coil, giving a thicker, higher‑output voice while retaining the familiar Strat mounting dimensions. The black bobbin and staggered pole pieces are typical of the TB‑4’s look, and its construction uses alnico magnets and overwound coils to achieve its characteristic output and tonal balance.

Electrically, the TB‑4 is voiced to deliver increased midrange and bass response compared with standard single coils, providing a fuller, punchier bridge voice that can push amplifiers harder and handle heavier styles without losing clarity. Its humbucking design cancels the 60‑cycle hum common to single coils, making it more suitable for high‑gain applications. The pickup is often paired with traditional single coils in the neck and middle positions, allowing a blend of classic Strat chime and more aggressive bridge tones when used with a five‑way selector.

Installation of the TB‑4 Trembucker requires a Stratocaster with the appropriate pickup route or modification to accept the humbucker footprint, as its physical size and mounting differ from standard single‑coil units. Once mounted, the TB‑4 can be operated with standard volume and tone controls and integrates into existing wiring schemes, giving players a straightforward upgrade path to a hotter, more powerful bridge voice without fundamentally altering the guitar’s control layout.
