Seymour Duncan SMB-4A 3 Coil Pickup vs Seymour Duncan SMB-5A 3 Coil Pickup
Both are hand-built Seymour Duncan 3-coil pickups for Music Man basses with identical switching and hum-canceling performance. The SMB-4A emphasizes upper-midrange sparkle (9.9 kHz peak) with a resonant, defined tone, while the SMB-5A prioritizes punchy mids and high output (4.4k ohms vs 4.18k) for cutting through dense mixes. Choose the SMB-4A for articulate, vintage-leaning definition; pick the SMB-5A for aggressive versatility and modern punch.
No sales tax on orders shipped outside California — total cost beats national retailers that charge sales tax in nearly every state.

Frequently asked questions
What's the real difference in output between these two?
The SMB-5A has a higher DC resistance at 4.4k ohms compared to the SMB-4A's 4.18k ohms per coil, resulting in noticeably greater output. This makes the SMB-5A louder and more aggressive, particularly in the midrange.
Are the tone-shaping capabilities identical?
Both pickups offer three identical switching modes (series, parallel, split) via a 3-way blade switch with full hum cancellation in all modes. The SMB-4A emphasizes upper-midrange presence (9.9 kHz peak), while the SMB-5A is voiced for punchy mids and articulate highs without a specified frequency peak.
Which is better for studio recording?
Both are suitable for studio work. The SMB-4A excels at capturing definition and sustain with its resonant peak; the SMB-5A works better if you need aggressive, cutting tones that sit forward in a mix. Choice depends on your target sound, not the pickup's capability.
Will either work with 5-string basses?
The SMB-5A explicitly states compatibility with both 4-string and 5-string Music Man basses. The SMB-4A is specified as a direct replacement for StingRay basses (1976-present), which historically includes 4-string models; verify your specific 5-string model before purchasing.
