Detail 01
Flatwound
The winding is a flat ribbon, not round wire. Your fingers slide silently and the tone reads darker and smoother.

Independent shopping perspective
The Korena take
A flatwound electric guitar set in medium light gauge. For players who want a smooth, quiet string surface rather than roundwound bite.
Strong match

- Players who want no finger squeak on recordings
- Anyone moving from roundwounds to a smoother left-hand feel
- Electric players wanting a darker, less zingy top end
Consider the trade-offs
When to look elsewhere
- Players who want bright, aggressive roundwound attack
- Anyone on a tight per-set budget
- Acoustic guitars — this is an electric set
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
Medium light gauge
A step down from mediums. Less tension under the fingers than a medium set, more than a true light set.
Detail 03
Electric guitar set
Built to drive magnetic pickups. Not a substitute for acoustic strings, which rely on bronze windings for volume.
Detail 04
Smooth winding surface
Nothing to catch on the fret crowns, so less fret grind and less grit trapped between the wraps.
Detail 05
$43.49 a set
Higher up front than a roundwound set. Flatwound players tend to change strings far less often.
Final check
Know before you order
- 01Strings only — no picks, winder or tools in the package
- 02A gauge change usually means resetting intonation and checking relief
- 03Expect a real tone shift if you are coming from roundwounds
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will flatwounds fit my regular electric guitar?
Yes, this is a standard six-string electric set. Only the winding surface differs from the roundwounds you are used to.
02How is medium light different from regular light?
Slightly more tension and mass than a light set, with a bit less than a medium. It sits between the two.
03Do flatwounds reduce finger noise?
Yes. The flat ribbon winding has no ridges for your fingertips to drag across, so sliding between chords is close to silent.
04Can I use these on an acoustic?
No. These are electric strings. An acoustic needs a bronze-wound set to drive the top properly.
