D'AddarioEJ25B Pro-Arte Composites Flamenco Guitar Strings - Black Nylon
Independent shopping perspective
The Korena take
Nylon flamenco strings with black-treated trebles. For classical or flamenco players who want a distinct look and a slightly different treble feel.
Strong match
Who this is for
- Flamenco players wanting a lighter, quicker treble response
- Classical guitarists after a visual contrast against a light fretboard
- Nylon-string players restringing a standard-scale classical
Consider the trade-offs
When to look elsewhere
- Steel-string acoustics — nylon needs a classical bridge and neck
- Players wanting the highest tension for heavy right-hand attack
- Anyone whose guitar has bridge pins rather than a tie block
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
Flamenco-oriented set
Chosen tension favors fast right-hand work and buzz-tolerant low action over maximum classical projection.
Detail 03
Composite construction
Composite material aims at more consistent intonation across the treble strings than plain nylon usually gives.
Detail 04
Nylon, not steel
Far lower tension than a steel set. Only fits a guitar built for nylon; steel would damage a classical top.
Detail 05
Full six-string set
One set restrings a guitar completely, no separate purchase for wound bass strings.
Final check
Know before you order
- 01Nylon strings stretch for days after install — expect repeated retuning at first
- 02Ties at the bridge, not bridge pins; know the knot before you start
- 03Black nylon can transfer a slight mark to light-colored fretboards over time
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these fit my acoustic guitar?
Only if it is a nylon-string classical or flamenco guitar. Do not fit nylon strings to a steel-string acoustic or the setup will not work.
02Do black nylon strings sound different from clear?
Yes. Black nylon is a different formulation and is usually described as warmer and rounder in the trebles than clear nylon.
03How long do they take to settle in tune?
Several days of playing and retuning. Nylon stretches far more than steel, so the first sessions need frequent tuning.
04Can I use these on a classical guitar, not flamenco?
Yes. Flamenco and classical guitars take the same nylon sets; the tension choice suits fast right-hand playing on either.
