What size cavity does the SM-3N fit?

The SM-3N is designed as a mini humbucker for narrow pickup cavities found in offset or compact-cavity instruments. Core housing measures 2.580" L × 1.085" W × 0.585" H, with overall dimensions of 3.174" L × 1.085" W × 0.876" including the mounting tab.

What tonal character should I expect from this neck pickup?

The SM-3N delivers articulate midrange response with a resonant peak at 7 kHz, clarity without harshness, and a warm, defined tone. Its balanced EQ profile (7 bass / 5 mid / 6 treble) and moderate output (6.29 kΩ) prioritize note separation and dynamic response, making it ideal for jazz, blues, and rock.

What does the four-conductor wiring allow me to do?

Four-conductor wiring unlocks coil-splitting and phase-reverse capabilities, giving you tonal versatility and the ability to expand your sonic palette without swapping pickups.

Is this pickup hand-wound, and what magnets does it use?

Yes, the SM-3N is hand-wound and wax-potted for microphonic feedback rejection. It uses Alnico V magnets paired with high-carbon steel blades per coil, delivering the refined response expected from professional-grade Seymour Duncan pickups.

Do I pay sales tax on this order?

Sales tax is collected only on orders shipped to California; orders shipped to any other US state are not charged sales tax at checkout when you buy direct from our website. Marketplaces collect sales tax as the facilitator in most states, so the same listed price can cost more there. Buyers remain responsible for any use tax their state applies.

Seymour Duncan SM-3N Seymourized Mini Humbucker 4-Conductor Neck Pickup

The SM-3N is a compact, hand-wound neck humbucker engineered to capture articulate midrange response and balanced output in confined pickup cavities. This Alnico V-loaded design is voiced specifically for neck position tracking, delivering clarity without harshness across the frequency spectrum. The four-conductor wiring unlocks coil-splitting and phase-reverse capabilities for session-ready tonal versatility without repatching.

Recording Tone & Output Character

The SM-3N exhibits a resonant peak at 7 kHz with a balanced EQ profile (7 bass / 5 mid / 6 treble) that maintains definition in neck position tracking while preserving warmth for layered arrangements. A DC resistance of 6.29 kΩ positions this pickup in the moderate-output range, ideal for capturing note separation and dynamic response in mix without saturation, particularly suited to clean and crunch tones that need to sit clearly in a full production.

Construction & Specifications

Hand-wound and wax-potted for microphonic feedback rejection—essential for studio recording without unwanted noise floor—this pickup measures 2.580" L × 1.085" W × 0.585" H in its core housing, with overall dimensions of 3.174" L × 1.085" W × 0.876" H including the mounting tab. The high-carbon steel blade design paired with Alnico V magnets delivers the refined response expected in professional tracking applications.
