Independent shopping perspective

The Korena take

A single A string for full-size cello, sold on its own rather than as a set. For replacing a broken or worn top string.

Strong match

Who this is for

  • Replacing a snapped A without buying a whole set
  • Full-size 4/4 cellos only
  • Players who wear out the top string faster than the rest

Consider the trade-offs

When to look elsewhere

  • Anyone needing a complete restring — this is one string
  • 3/4, 1/2 or smaller student cellos
  • Upright bass or violin players

What matters in use

The specifications, translated

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

Sold as a single A string

You get the top string only. The D, G and C are separate purchases.

Detail 02

4/4 sizing

Cut for a full-size cello. On a smaller body the winding hits the peg or pin wrong.

Detail 03

A string position

Highest of the four. Carries most melodic playing, so it takes the most bow wear.

Detail 04

Thomastik Superflexible line

Mixing it with other brands on the remaining three strings gives uneven tension and response across the set.

Detail 05

Per-string price

Buying the four singles individually costs more than the matched set. Worth checking before a full restring.

Final check

Know before you order

  1. 01Confirm your cello is 4/4 — measure the back length before ordering
  2. 02One string only; no set, no rosin, no tools included
  3. 03New strings stretch for several days and need repeated retuning

Product questions

Before you decide

Straight answers to the questions shoppers most often ask about this product.

01Is this a full set of cello strings?

No. This is the A string alone. The D, G and C are sold separately.

02Will it fit a 3/4 cello?

No. It's cut for a 4/4 instrument. A 3/4 cello needs the 3/4 version of the string.

03How long does it take to settle in?

Expect frequent retuning for the first few days of playing while the string finishes stretching.

04Can I mix this with a different brand on the other strings?

You can, but tension and feel will differ string to string. Matching the whole set keeps the response even.
