Scale-length specific. A 1/2 or 3/4 string will sit at the wrong tension and pitch.
Detail 02
Settles into pitch fast and stays there. Less warmth than gut or synthetic core.

Detail 04
D'Addario's student line. Built for durability and tuning stability over tonal nuance.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. Buy the 1/2 size version. Wrong-size strings sit at incorrect tension and may not reach pitch or may break.
No. This is the A string alone. The 1/4 size set is sold separately.
Steel core settles quickly — usually a few days of playing and retuning, faster than synthetic or gut strings.
Yes, if the others are still in good shape. If they're all old, replacing the set keeps tone even across strings.
