Seymour Duncan SMB-5A 5-String Alnico Magnet Pickup For Music Man

The SMB-5A is a hand-built 5-string Music Man pickup engineered for aggressive articulation and focused midrange punch. Designed by Seymour Duncan in Santa Barbara, this alnico-magnet design cuts through dense mixes with clarity while maintaining the tight, controlled response that active bass players demand.

Tone & Magnetic Characteristics

Alnico V rod magnets deliver a warm, vintage-influenced core with excellent sustain and note definition across the fundamental frequencies. The 8.35 kHz resonant peak provides upper-midrange presence without harshness, while the EQ profile of 8/8/5 (Bass/Mid/Treble) emphasizes low-end body and midrange aggression with controlled high-end extension.

Construction & Wiring

This pickup features vacuum wax potting to eliminate microphonic feedback and ensure consistent performance under stage conditions. The four-conductor leadwire allows flexible wiring configurations, and a 5.01 kΩ DC resistance (in parallel) positions this pickup as a moderate-output design suited to both passive and active preamp setups.
