Seymour Duncan SRB‑1B & SRB‑1N, (Used)

The Seymour Duncan SRB‑1B is a replacement bridge humbucking pickup designed for Rickenbacker 4000‑series basses. It uses Alnico 5 flat‑blade magnets to provide strong output and enhanced sustain while maintaining the clarity and definition characteristic of Rickenbacker basses. The pickup is wax-potted to reduce microphonics and comes with a shielded 4-conductor lead to support a variety of wiring configurations.

The Seymour Duncan SRB‑1N serves as the matching neck-position humbucker for Rickenbacker basses. It features two ceramic bar magnets and a specially designed winding to deliver warmth, clarity, and a broad harmonic range compared to standard neck pickups. The unit is vacuum wax-potted to minimise feedback and is fitted with a chrome-plated nickel-silver cover, with a 4-conductor cable for flexible wiring, including parallel or split-coil options.

Together, the SRB‑1B and SRB‑1N provide a balanced tonal pairing, allowing for strong, articulate bridge tones and warm, full neck tones. Both pickups are designed to enhance the natural character of Rickenbacker basses while offering reliability and durability suitable for both studio and stage performance.
