Detail 01
Composite trebles
Denser than plain nylon, so the treble strings push more volume and hold pitch more consistently. Slightly brighter attack.

D'AddarioEJ45C Pro-Arte Composites Normal Classical Guitar Strings
1/4
Independent shopping perspective
The Korena take
Normal-tension classical strings with composite trebles instead of plain nylon. For classical and nylon-string players who find standard trebles thin or unfocused.
Strong match
Who this is for
- Classical players wanting more projection from the treble strings
- Nylon-string guitars with tie-block bridges
- Players whose plain nylon G sounds dull or dead
Consider the trade-offs
When to look elsewhere
- Steel-string acoustics — nylon strings won't drive the top
- Players who want the softest, warmest traditional nylon feel
- Anyone needing high tension for heavy right-hand attack
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
Normal tension
The middle option. Balanced feel under the fingers without the stiffness of hard tension or the looseness of light.
Detail 03
Ball end
Tie at the bridge rather than a loop knot. Faster restringing and the strings won't slip loose at the block.
Detail 04
Nylon construction
Requires a guitar built for nylon. Steel-string necks and bridges are braced for far higher tension.
Final check
Know before you order
- 01Nylon strings stretch for days — expect repeated retuning at first
- 02Ball ends won't work on bridges that need a tied knot
- 03Set only — no string winder or tuner included
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I put these on a steel-string acoustic?
No. Nylon strings don't generate enough tension to drive a steel-string top, and the bridge and nut are cut differently. The guitar needs to be built for nylon.
02How long until they stay in tune?
Nylon keeps stretching after installation. Plan on a few days of frequent tuning before the set settles, and stretch each string by hand to speed it up.
03What makes composite trebles different from plain nylon?
The material is denser, so the treble strings project more and stay truer to pitch fret to fret. The trade-off is a slightly brighter, less mellow tone.
04Will these work on a flamenco guitar?
They'll fit any nylon-string guitar. Normal tension gives moderate action height; flamenco players who want lower action and more attack often prefer harder tension.
