Seymour Duncan SMB-4DS 4-String Ceramic Magnet Pickup & 3-Band Tone Circuits For Music Man

The SMB-4DS captures punchy, articulate bass with responsive active EQ controls that translate both aggressive playing and nuanced dynamics into clear, defined recordings. This complete pickup and electronics package integrates seamlessly into your Music Man StingRay bass as a straightforward drop-in installation, unlocking an expanded sonic palette for overdubs, mixing flexibility, and genre-specific session work without requiring extensive modifications.

Pickup & Magnetic Design

The 4-string ceramic bar magnet architecture delivers bright, cutting highs and solid low-end definition that cuts through dense mixes and sits naturally alongside other instruments. Hum-canceling construction ensures clean, noise-free output ideal for controlled recording environments, while the 2.6 kΩ per coil DC resistance and 9.4 kHz resonant peak (in parallel) produce articulate midrange presence that translates across slap, fingerstyle, and pick techniques in the mix.

Active Tone Shaping & Electronics

The 3-band active EQ circuit provides independent sculpting of Bass, Midrange, and Treble at ±7, ±8, and ±6 dB ranges respectively, allowing precise tonal refinement for different session contexts without unwanted coloration. Low noise, low distortion, and high headroom characteristics preserve dynamic range and recording integrity, while the proprietary Slap Switch adds a fourth layer of tonal flexibility for adapting quickly between playing styles and song sections.
