Detail 01
Active design
Onboard preamp needs a 9V battery. Output stays consistent and the noise floor drops, but the battery must be changed.

Seymour DuncanBlackouts AHB-1s 7-String Phase II Active Humbucker neck & bridge set Black
Independent shopping perspective
The Korena take
Active neck-and-bridge humbucker set for 7-string guitars, with onboard preamp and Alnico V bar magnets. For extended-range players wanting a tight, low-noise high-gain platform.
Strong match
Who this is for
- 7-string players running high gain who want a quiet noise floor
- Down-tuned rhythm work needing a tight, defined low B
- Replacing a full 7-string pickup set in one go
Consider the trade-offs
When to look elsewhere
- 6-string guitars — the spacing and size won't line up
- Players who want passive pickups that respond to volume rolloff the same way
- Anyone unwilling to route a battery cavity if there isn't one
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 bar magnets
Alnico gives more harmonic warmth and note bloom than ceramic. Less brittle on the top end at high gain.
Detail 03
6/5/8 bass/mid/treble
Scooped mids with a lifted treble and firm bass. Aggressive and cutting rather than mid-forward and vocal.
Detail 04
Bridge resonant peak 530 vs neck 750
The neck unit peaks higher for lead clarity; the bridge sits lower and thicker for rhythm weight.
Detail 05
Three-conductor cable
More wires than a passive swap. Wiring must follow the active layout, including the stereo output jack for battery switching.
Detail 06
Neck and bridge set
Both positions included and voiced to match. No hunting for a companion pickup or mismatched output between slots.
Final check
Know before you order
- 019V battery and a stereo output jack are required for the active circuit.
- 02Needs space for a battery — routing a cavity may be necessary on some guitars.
- 03Active pickups need their own volume and tone pot values, not standard passive ones.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these fit my 6-string?
No. These are 7-string pickups. The housing is wider and the pole spacing matches a 7-string bridge, so they won't seat in a 6-string rout.
02How long does the battery last?
A 9V powers the circuit only while a cable is plugged in, since the stereo jack acts as the switch. Unplug when not playing and one battery lasts a long stretch.
03Can I use my existing pots?
Usually not. Active circuits call for different pot values than passive pickups. Plan on installing the pots specified for the active wiring.
04Are these good for clean tones?
They stay quiet and even when clean, with a scooped, treble-forward voice. Players who want a warm, mid-rich clean will find them bright.
