Detail 01
Hard tension
Stiffer under the fingers and higher pull on the neck. More volume and attack, less give on aggressive right-hand strokes.

D'AddarioEJ46TT ProArte DynaCore Hard Classical Guitar Strings
1/4
Independent shopping perspective
The Korena take
Hard-tension classical guitar strings with a composite DynaCore basses. For nylon-string players who want more volume and steadier tuning than standard sets.
Strong match
Who this is for
- Classical or flamenco players who want more projection
- Nylon-string guitars that sound loose with normal-tension sets
- Players fighting frequent retuning during a performance
Consider the trade-offs
When to look elsewhere
- Steel-string acoustics or electrics — nylon strings only
- Beginners with tender fingers; hard tension is stiffer to press
- Older or lightly built guitars not rated for higher string tension
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
DynaCore composite bass strings
Multifilament core instead of plain nylon under the winding. Holds pitch better and settles in faster than traditional basses.
Detail 03
Classical guitar scale
Made for a nylon-string guitar with a tie-block bridge. They will not work on a steel-string with bridge pins.
Detail 04
ProArte treble strings
Clear nylon trebles, sorted for consistent diameter, so intonation stays even up the fretboard.
Detail 05
$18.99 per set
Mid-tier price for classical strings. The composite basses are where the extra cost over plain nylon sets goes.
Final check
Know before you order
- 01Classical strings tie at the bridge — no ball ends, so allow time to tie them
- 02Trebles still stretch for a few days; the basses settle faster
- 03Hard tension raises neck pull — not for fragile or vintage-built instruments
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use these on a steel-string acoustic?
No. These are nylon classical strings for a tie-block bridge. A steel-string guitar needs ball-end steel strings.
02What does hard tension actually feel like?
Stiffer under the left hand and more resistance for the picking fingers. In return you get more volume and a firmer attack.
03What is DynaCore?
D'Addario's composite core used under the bass string windings in place of plain nylon. It holds tuning more steadily than a traditional core.
04Should I start with hard or normal tension?
Normal tension is the safer default if you're unsure. Move to hard when you want more volume or find normal too loose.
