Roswell Pickups LAF9 Seraphim Custom Bridge Matt Chrome Humbucker Pickup

Bridge Humbucker Pickup with Alnico 5 + Ceramic Hybrid Magnet

The Roswell Pickups LAF9 Seraphim Custom Bridge Matt Chrome is a passive humbucker built specifically for the bridge position of an electric guitar. It uses a hybrid magnet configuration that pairs an Alnico 5 bar with a ceramic element, a combination less common than single-magnet designs and aimed at players who want both warmth and bite from the bridge slot. The Matt Chrome cover gives the pickup a low-reflectivity finish that blends into natural-finish guitars and hardware kits without glare under stage lighting.

What Sets the LAF9-B4 Apart in the Seraphim Range

Inside the bridge version sits an Alnico 5 bar magnet working alongside a ceramic magnet, a hybrid layout that pushes output higher than a pure Alnico design while keeping the harmonic character of the Alnico 5. The 4-conductor shielded output wire is a deliberate choice for guitarists who want to wire the pickup with coil-split, phase or series/parallel options using a push-pull pot or mini toggle. The Matt Chrome cover is matched to the rest of the Seraphim Custom range, so it pairs cleanly with the matching LAF9-N4 neck model for a uniform look across both slots.

Magnet Configuration — Output and Tonal Character

The magnet layout is the single biggest factor in how a humbucker behaves under the fingers, and this model uses a hybrid that combines two magnet types in one housing.

• Magnet: Alnico 5 Bar + Ceramic — the Alnico 5 contributes warmth and string definition, while the ceramic element adds punch and a tighter low end
• DC Resistance: 13.3K — a high-output reading that drives a tube amp into saturation more readily than lower-output pickups

Wiring and Installation — Drop-In Bridge Replacement

Wiring flexibility matters as much as raw tone for players who like to rewire their instrument, and the output cable on this pickup is built for that.

• Output Wire: 4-Conductor Shielded (4P Shield) — exposes both coil starts and finishes, enabling coil tap, series/parallel switching and phase reversal
• Approximate Weight: 147 g — light enough to avoid altering the balance of a standard electric guitar when mounted in the bridge route

Build, Cover and Physical Specs

The physical package is a standard humbucker footprint, so installation is a straight swap in most electric guitars routed for two humbuckers.

• Cover Finish: Matt Chrome — non-reflective surface that resists fingerprints and stage-light glare
• Position: Bridge — wound and voiced specifically for the bridge slot, not intended as a neck pickup
