Detail 01
Flatwound
Polished ribbon winding instead of round wire. Smooth under the fingers, much less squeak, darker and shorter-sustaining than roundwound.

ThomastikJS110 Flatwound Extra Light Jazz Swing Guitar Strings
1/2
Independent shopping perspective
The Korena take
Flatwound jazz set for electric guitar, extra light gauge. For archtop and hollowbody players who want a dark, smooth string with almost no finger noise.
Strong match
Who this is for
- Archtop and hollowbody players chasing a dark, woody jazz tone
- Players who slide chords and hate squeak on wound strings
- Fretboard-heavy playing where light tension keeps the left hand easy
Consider the trade-offs
When to look elsewhere
- Players who want bright, ringing sustain and pick attack
- Anyone doing heavy bends and aggressive rock rhythm work
- Shoppers replacing strings often — these cost several times a roundwound 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
Extra light gauge
Lower tension than standard jazz sets. Easier bends and less pull on the neck, but a thinner, less thumpy low end.
Detail 03
Jazz Swing series
Voiced for a warm, mid-focused tone rather than treble sparkle. Suits amps set clean with the tone rolled back.
Detail 04
Electric guitar strings
Magnetic pickup use. They will not drive an acoustic soundboard the way bronze acoustic strings do.
Detail 05
Price per set
Well above a typical roundwound set, but flatwounds hold their tone far longer, so change intervals stretch out.
Final check
Know before you order
- 01Check the scale length and string spacing on your guitar before ordering
- 02Flatwounds sit differently in the nut slots — a setup may be needed
- 03Extra light shifts tension; expect to reset intonation and truss rod
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, any standard electric with a magnetic pickup takes them. Confirm scale length and check that the nut slots fit the string diameters without binding.
02Why are flatwounds so much quieter when I slide?
The outer winding is a flat ribbon rather than round wire, so the fingertip has no ridges to catch on. That is most of what you pay for.
03How long do these last?
Longer than roundwounds. The smooth surface traps less skin and grime, so tone holds up over months of regular playing rather than weeks.
04Is extra light too floppy for standard tuning?
Not for jazz chording and single-note lines. If you dig in hard with a pick or tune down, a heavier gauge holds pitch better.
