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
One string in the packet. The other three are separate purchases at similar per-string cost.
Detail 02
Cut for a full-size violin. On a 3/4 or smaller, the winding will sit wrong at the peg or tailpiece.
Detail 03
Strings in a line are tensioned to balance each other. Mixing lines can leave the A louder or duller than its neighbours.
Detail 04
Roughly a quarter of a set. If two strings are already tired, a full set is the better spend.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It is the A string on its own. The E, D and G are sold separately.
No. It is cut for 4/4. A smaller instrument needs the matching fractional size.
You can, but tension and response vary between lines, so the A may not match the volume of the others.
New strings stretch. Plan on retuning several times over the first day or two before it holds pitch.
