Detail 01
A string only
One string, not a set. The other three stay as they are, so match brand and gauge carefully.

Independent shopping perspective
A single Larsen Chromesteel A string for full-size cello, strong gauge. For cellists replacing a broken or dead A rather than buying a full set.

Strong match

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, not a set. The other three stay as they are, so match brand and gauge carefully.
Detail 02
Steel-based core and winding. Holds pitch quickly after installation and resists humidity swings better than gut.
Detail 03
Higher tension than medium. More volume and projection, stiffer under the fingers, more load on the instrument.
Detail 04
Cut for cello, not violin or viola. Length and ball end are specific to the instrument.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. This is the A string alone. If you need all four, buy them individually or as a set.
It raises tension. You get more volume and a firmer feel under the fingers, at the cost of easy response and added pressure on the instrument.
It is cut for 4/4. On a smaller cello the speaking length is wrong and tension will be off.
Steel-core strings stabilize fast. Expect it to hold pitch within a day or so of stretching and retuning.
