Detail 01

ThomastikSpirocore 4/4 Size Cello Strings 4/4 C String, Tungsten
Independent shopping perspective
The Korena take
A single tungsten-wound C string for a 4/4 cello. For players replacing just the low string, not buying a full set.
Strong match
Who this is for
- Replacing a worn or broken low C on a full-size cello
- Players already using this string line on the other three
- Cellists who want a denser, faster-responding low string
Consider the trade-offs
When to look elsewhere
- Anyone needing all four strings — this is one string
- Smaller cellos: 3/4, 1/2 and below
- Players wanting a matched set from a single purchase
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 02
Tungsten winding
Tungsten is very dense, so the string reaches low C at a thinner diameter and speaks faster under the bow.
Detail 03
4/4 size
Cut for a full-size cello string length. A 3/4 instrument needs its own shorter version.
Detail 04
Thomastik Spirocore
A specific string line. Mixing lines across the four strings can leave the C feeling different from its neighbors.
Detail 05
$180.40 for one string
Low strings cost the most in a set. This is why many cellists replace the C on its own schedule.
Final check
Know before you order
- 01One string in the package — no set, no rosin, no tools
- 02Loosen and replace only this string so the sound post stays put
- 03Check your cello is 4/4 before ordering
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 C string alone — the lowest of the four. The G, D and A are sold separately.
02Will it fit a 3/4 cello?
No. It is sized for a 4/4 instrument. On a smaller cello the winding will not line up at the nut and tailpiece.
03What does the tungsten winding change?
Tungsten's density lets the string hit low C while staying thinner, which makes it quicker to speak under the bow.
04Can I mix this with another brand's strings?
You can, and many players do. Just expect the C to feel and respond differently from the three around it.
