  • Alnico 5 magnets deliver enhanced clarity and warm sustain
  • Balanced EQ (8/8/5) keeps all frequencies present without aggression
  • Higher resonant peak (9.9 kHz) adds articulate treble response
  • Direct replacement for standard 4-string Music Man Stingray basses

Why choose Seymour Duncan SMB-5D 5-String Ceramic Magnet Pickup For Music Man

  • Engineered specifically for 5-string applications with proper string spacing
  • Ceramic magnets and aggressive EQ (7/8/6) cut through dense mixes
  • Hum-canceling architecture rejects 60Hz interference
  • Lower DC resistance (2.9 kΩ) provides tighter, more controlled output

Frequently asked questions

What's the main tonal difference between alnico and ceramic magnets here?

The alnico SMB-4A emphasizes smooth clarity and sustain with a balanced presence, making it ideal for funk and rock where warmth matters. The ceramic SMB-5D pushes midrange aggression and presence-peak cut, suiting modern rock and metal where cutting through a mix is priority.

Can I use either pickup on my instrument?

No. The SMB-4A is built for 4-string Music Man basses only. The SMB-5D is purpose-designed for 5-string Music Man basses. Using either on the wrong instrument will result in improper string coverage and poor tone.

Which handles high-volume gigging better?

Both are vacuum wax potted to eliminate squeal at any volume. The SMB-5D's hum-canceling design and lower output impedance (2.9 kΩ) make it more stable in electrically noisy live environments, while the SMB-4A's balanced EQ handles volume smoothly without harshness.

Do these offer wiring flexibility?

Yes. The SMB-4A supports series, parallel, and split-coil configurations via 4-conductor wiring. The SMB-5D also features 4-conductor wiring for full flexibility on any 5-string Music Man circuit.
