Detail 01
Trembucker spacing
Pole pieces sit farther apart than a standard humbucker so they line up under the strings on wide tremolo bridges.

Independent shopping perspective
The Korena take
Trem-spaced bridge humbucker in white. The wider pole spacing is for guitars whose bridge spreads the strings farther apart than a standard stop-tail.
Strong match
Who this is for
- Guitars with a wide-spaced tremolo bridge at the bridge position
- Matching white pickups to a white pickguard or hardware scheme
- Replacing a stock bridge pickup where poles miss the outer strings
Consider the trade-offs
When to look elsewhere
- Narrow-spaced stop-tail bridges — poles will sit outside the E strings
- Neck position, which needs a lower-output pickup
- Anyone unwilling to solder or pay for installation
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
Bridge position
Wound hotter to make up for the smaller string movement near the bridge. It will overpower a neck pickup if installed there.
Detail 03
White bobbins
Stands out against dark finishes and matches white hardware. A metal cover would hide it, defeating the point.
Detail 04
Full-size humbucker route
Needs an existing humbucker cavity and matching ring or pickguard cutout. Spacing affects pole alignment, not the outside dimensions.
Detail 05
$99
Same price tier as the standard-spaced models. You pay for the correct spacing, not extra features.
Final check
Know before you order
- 01Measure string spacing at the bridge saddles first — the wrong spacing misaligns the poles
- 02No cover, pots, springs beyond mounting hardware, or wiring harness included
- 03Requires desoldering the old pickup; budget for a tech if you don't solder
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How do I know if I need trem spacing?
Measure between the low and high E strings at the bridge saddles. Wide-spaced tremolo bridges need it; narrow stop-tail bridges usually don't.
02Can I use it on a hardtail guitar?
It will mount, but the outer poles may sit past the E strings, weakening those two strings relative to the middle four. Check spacing first.
03Does the white plastic yellow over time?
Exposed bobbins can discolor with sun and smoke exposure over years. Keeping the guitar in a case slows it.
04Is it the same pickup as the standard-spaced version?
Same model line, different pole spacing. The choice is about matching your bridge, not about a different sound.
