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
Cut for full-size cello string length. A fractional cello will leave too much or too little winding at the peg.
Detail 02
Only the D. Mixing a new D with three aged strings gives an uneven response across the instrument.
Detail 03
Synthetic core rather than steel, so it needs a break-in period and drifts with temperature and humidity more than steel.
Detail 04
Cello strings use far more material at greater length and tension, which is most of the cost difference.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. This is cut for 4/4. A 3/4 cello needs the matching fractional string or it will not seat correctly.
No. This is the D string only. A, G and C are separate purchases.
Depends entirely on hours played. Replace when the string sounds dull, responds poorly under the bow, or will not hold pitch.
No, but keep the bridge upright and the soundpost undisturbed while changing. Change one string at a time to keep tension on the instrument.
