Detail 01
Ball end
Anchors like an acoustic string instead of tying a knot at the bridge. Faster changes, but the bridge has to accept it.

Ernie Ball2409 Ernesto Palla Nylon Ball End Classical Acoustic Guitar Strings - (28-42)
Independent shopping perspective
The Korena take
Nylon classical guitar strings with ball ends, 28-42. For classical or nylon-string players who don't want to tie knots at the bridge.
Strong match
Who this is for
- Classical or nylon-string guitars with a bridge that accepts ball ends
- Players who find tie-block knotting slow or fiddly
- Keeping a cheap spare set in the case
Consider the trade-offs
When to look elsewhere
- Steel-string acoustics — nylon on a steel-string setup won't work
- Players who need a specific tension the 28-42 range doesn't hit
- Anyone whose bridge is designed only for tied strings
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
Nylon
Softer under the fingers than steel, mellower attack, lower tension. Nylon also stretches for days before it holds pitch.
Detail 03
28-42 gauge
The measured range of the set. Use it to match tension when you're comparing against your current strings.
Detail 04
Classical guitar strings
Built for a nylon-strung instrument with a wider, flatter neck. Not a replacement for steel strings on the same guitar.
Detail 05
$9.99 per set
Entry-level pricing for nylon. Cheap enough to change often, which matters since nylon dulls gradually rather than dying suddenly.
Final check
Know before you order
- 01Confirm your bridge takes ball ends — many classical guitars are tie-block only
- 02Nylon stretches heavily; expect several days of retuning before pitch settles
- 03Never fit these to a steel-string guitar, and never the reverse
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What does ball end mean on nylon strings?
The string has a fixed bead at one end, so it anchors in the bridge instead of being tied. It cuts string-change time considerably.
02How long until they stay in tune?
Nylon keeps stretching for several days after fitting. Tune often at first. Gently pulling each string helps pull the stretch out sooner.
03Can I put these on my acoustic guitar?
Only if it's a nylon-string instrument. A steel-string acoustic is braced and set up for steel tension and won't play right with nylon.
04What does 28-42 refer to?
The gauge range across the set. It's the number to compare when you want a similar feel to strings you already like.
