Detail 01
Quarter-pound pole pieces
Larger magnet slugs push a wider, stronger magnetic field, so output and low end climb over a standard single-coil.

Seymour DuncanSJM-3 Quarter-Pound Jazzmaster Pickup Black Neck
Independent shopping perspective
The Korena take
A neck-position Jazzmaster replacement pickup with oversized pole pieces for higher output. For offset players who want more push and thickness up front.
Strong match
Who this is for
- Offset guitars where the neck pickup sounds thin or weak
- Players who want a fatter, louder clean neck tone
- Pairing with a stock bridge pickup for contrast
Consider the trade-offs
When to look elsewhere
- Players chasing quiet, glassy vintage Jazzmaster neck tone
- Strat, Tele or humbucker routes — the shape will not fit
- Anyone unwilling to solder or pay a tech
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Neck position wind
Wound and voiced for the neck slot only. It will sound muddy and unbalanced if mounted at the bridge.
Detail 03
Jazzmaster format
Wide, flat soapbar footprint. It drops into a Jazzmaster route and nothing narrower without new routing.
Detail 04
Single-coil design
Open coil, so it hums under fluorescent lights and near monitors unless the guitar is well shielded.
Detail 05
Black cover
Cosmetic only. Matches black hardware and dark pickguards; no effect on tone or fit.
Final check
Know before you order
- 01Sold as one pickup — no bridge pickup, wiring harness or pickguard included
- 02Requires soldering to your pots and switch, plus a pickup height reset
- 03Higher output can unbalance volume against a stock bridge pickup
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my Squier Jazzmaster?
It fits a standard Jazzmaster pickup route and pickguard opening. Measure your existing pickup's footprint and mounting screw spacing first, since some offsets ship with narrower non-standard pickups.
02Is this the bridge or neck version?
Neck. It is wound for the neck position. Buy the matching bridge model separately if you want the pair.
03Does it hum?
Yes. It is a single-coil, so it picks up 60-cycle hum from lights, screens and transformers. Shielding the control cavity helps but will not eliminate it.
04Do I need new pots?
Not required. It works with standard pots, though the extra output can make the volume taper feel steeper than the pickup it replaces.
