What matters in use
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 01
Holds pitch better than synthetic core and lasts longer, but the response is more direct and less warm.
Detail 02
A wound E instead of plain steel. Less whistling and a smoother feel under the finger, slightly less brilliance.
Detail 03
Cut for full-size violin scale. On a smaller instrument the string length will be wrong.
Detail 04
All four strings — E, A, D and G — so the whole instrument changes voice at once, not just one string.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes. It is a complete 4/4 set with E, A, D and G.
A wound E cuts down the whistling that plain steel E strings can produce, and feels smoother under the finger. It trades a little brightness for that.
No. These are cut for 4/4 scale. A fractional instrument needs strings matched to its size.
Steel holds tuning longer and lasts longer. Synthetic core generally feels softer under the bow and reads warmer. This is a durability-first choice.
