Detail 01
20.26k ohms DC resistance
That figure covers both stacked coils, so it reads high; the audible output is hot but not that hot.

Seymour DuncanSTK-S9 Hot Stack Plus - Bridge Pickup Black Bridge
Independent shopping perspective
The Korena take
A stacked single-coil-sized humbucker for the bridge, hum-free with high output. For Strat-style players who want more push without a routing change.
Strong match
Who this is for
- Strat bridge slots where 60-cycle hum ruins recordings
- Pushing an amp harder from a single-coil-sized pickup
- Players who want more mids than a stock bridge single
Consider the trade-offs
When to look elsewhere
- Chasing a classic thin, glassy vintage Strat bridge tone
- Guitars with a humbucker-sized bridge route already
- Players who want low output for pedal-driven clean sounds
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
Alnico V rod magnets
Firmer and brighter than Alnico II, with stronger attack and tighter low end.
Detail 03
3.23 kHz resonant peak
The presence bump sits fairly low, so the top end is smoothed rather than spiky.
Detail 04
Stacked design
Second coil sits under the first, cancelling hum while keeping a single-coil footprint.
Detail 05
3-conductor shielded cable
Extra leads allow wiring options beyond standard; also lets a tech reverse the coil connection.
Detail 06
EQ 5/7/4
Mid-forward voicing with restrained treble — thicker than a stock single, not scooped.
Final check
Know before you order
- 01Pickup only — no pickguard, pots, switch or output jack included
- 02Higher output may unbalance your neck and middle pickups on the switch
- 03Requires soldering into your existing harness; shielded cable needs a proper ground
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will it fit my Strat pickguard?
It is single-coil sized for a standard bridge slot. No routing or pickguard change is needed for a conventional Strat-style bridge position.
02Is it really hum-free?
The stacked second coil cancels hum the way a humbucker does, so single-coil buzz is not part of the sound.
03Why does the resistance read over 20k?
Stacked pickups measure both coils in series, so the number is much higher than a single coil's. It is not a direct output comparison.
04Can I use it in the neck position?
It is voiced and wound as a bridge pickup. In the neck it will sound thick and loud relative to the other positions.
