What is the DC resistance and resonant peak of this pickup?

The SMB-4D has a DC resistance of 2.6 kΩ per coil and a resonant peak at 9.4 kHz in parallel configuration, emphasizing upper-midrange articulation and punch.

Is this pickup suitable for jazz or mellow tones?

No—the SMB-4D is optimized for funk, rock, and aggressive studio work. Its ceramic magnets and hot output are designed for clarity and presence, not the warm, smooth character preferred in jazz.

What wiring options does the shielded 4-conductor cable support?

The shielded 4-conductor leadwire provides flexibility for series, parallel, or split configurations, allowing you to shape the tone to suit your rig and playing style.

How does Seymour Duncan prevent noise in this pickup?

The SMB-4D uses vacuum wax potting to eliminate microphonics and Forbon flatwork for superior durability, ensuring a quiet, noise-free signal whether you're on stage or in the studio.

Is this hand-built and made in the USA?

Yes—the SMB-4D is hand-built in Santa Barbara, California, and manufactured in the USA.

Seymour Duncan SMB-4D 4-String Ceramic Magnet Pickup For Music Man

The SMB-4D delivers punchy, articulate output with the aggressive character that ceramic magnets are known for. This dual-coil design cuts through the mix with clarity and presence, making it essential for tracking sessions where definition and snap are non-negotiable. Hand-built in Santa Barbara, this pickup brings professional-grade construction to your Music Man bass recordings.

Tone & Output

Ceramic bar magnets paired with a 2.6 kΩ DC resistance per coil produce a hot, responsive signal with excellent sustain. The 9.4 KHz resonant peak emphasizes upper-midrange articulation, delivering punch and clarity that sits well in dense mixes without sacrificing low-end definition—ideal for layered bass tracking and post-production mixing.

Design & Construction

Dual-coil configuration with arched pole pieces ensures balanced magnetic field and consistent response across all four strings. Vacuum wax potting and Forbon flatwork eliminate microphonic noise, while the shielded 4-conductor leadwire provides flexibility for series, parallel, or split configurations to suit your recording chain and mixing needs.
