Detail 01
Flatwound
The winding is a smooth ribbon instead of round wire. Almost no finger squeak, and a darker, rounder tone.

ThomastikJS113 Medium Flatwound Jazz Swing Electric Guitar Strings
1/8
Independent shopping perspective
The Korena take
Flatwound electric guitar strings in medium gauge. For players who want a smooth, dark, low-noise string rather than modern brightness.
Strong match
Who this is for
- Archtop and hollowbody players chasing a traditional jazz tone
- Recording where fret squeak shows up in the track
- Players who slide a lot and dislike wound-string scrape
Consider the trade-offs
When to look elsewhere
- Rock or metal players who need bite and harmonic sparkle
- Anyone who bends a full step regularly — medium flats fight back
- Guitars set up for light gauge without a truss rod adjustment
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 gauge
Higher tension than a standard light set. Stiffer feel, stronger fundamental, harder to bend.
Detail 03
Electric guitar set
Built for magnetic pickups on a standard-scale electric. Not an acoustic or classical set.
Detail 04
$46 a set
Several times the cost of a roundwound set. Flats also last far longer before going dull.
Detail 05
Smooth winding surface
Collects less sweat and grime in the winding grooves, so tone stays consistent much longer.
Final check
Know before you order
- 01Moving from lights to mediums usually needs a truss rod and intonation check.
- 02Nut slots cut for light gauge may bind on the thicker plain strings.
- 03Flats need little to no stretching-in and settle fast.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will flatwounds work on a solidbody, not just a hollowbody?
Yes. They fit any standard-scale electric. You get the same smooth feel and darker voice, just without the hollowbody resonance.
02How long do flatwounds last?
Much longer than roundwounds. The smooth surface traps far less debris, so many players go months between changes.
03Can I bend on medium flatwounds?
You can, but tension is high and the top strings resist. Players who bend constantly usually prefer a lighter set.
04Do flatwounds reduce fret wear?
The smooth winding is gentler on frets than the ridged surface of a roundwound, and it eliminates most sliding noise.
