Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. This is the D string alone. The A, G and C are sold separately.
No. It's cut for 1/2-size string length. A 3/4 cello needs a 3/4 string.
Steel core stretches very little, so it holds pitch within a few tunings of installation.
If the others are equally worn, yes — a single fresh string can sound brighter than its neighbors.
