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

The SMB-4DS delivers a punchy, articulate response with responsive active EQ controls that reward both aggressive playing and nuanced dynamics. This complete pickup and electronics package fits seamlessly into your Music Man StingRay bass, offering a straightforward drop-in installation that transforms your instrument's sonic palette without requiring extensive modifications.

Pickup & Magnetic Design

The 4-string ceramic bar magnet architecture provides bright, cutting highs and solid low-end definition. Hum-canceling construction ensures clean output even in electrically noisy environments, while the 2.6 kΩ per coil DC resistance and 9.4 kHz resonant peak (in parallel) yield articulate midrange presence ideal for slap, fingerstyle, and pick playing.

Active Tone Shaping & Electronics

The 3-band active EQ circuit provides independent control of Bass, Midrange, and Treble at ±7, ±8, and ±6 dB ranges respectively, allowing precise tonal sculpting without coloration. Low noise, low distortion, and high headroom characteristics preserve your instrument's natural dynamics, while the proprietary Slap Switch adds a fourth layer of tonal flexibility for genre-specific playing styles.
