ThomastikSpirocore 4/4 Size Cello Strings 4/4 C String, Silver
Independent shopping perspective
The Korena take
A single 4/4 cello C string from Thomastik's Spirocore line, silver-wound. For players replacing the low C specifically, not restringing a whole cello.
Strong match
Who this is for
- Replacing a worn or dead low C on a full-size cello
- Players who already run Spirocore and need the C again
- Keeping a spare low C on hand
Consider the trade-offs
When to look elsewhere
- Anyone restringing all four strings — buy per string
- Cellos smaller than 4/4
- Budget-minded students; this is one of the pricier singles
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
Silver winding
Spirocore Cs come in more than one winding. Order the silver version only if that is what you had.
Detail 03
4/4 size
Cut for full-size cello string length. Wrong length on 3/4 and smaller instruments.
Detail 04
$162.90 for one string
The C is the most expensive string on the instrument. Replace it only when it is actually dead.
Detail 05
Spirocore line
Mixing a Spirocore C under other-brand upper strings changes how evenly the cello responds across registers.
Final check
Know before you order
- 01Confirm you want silver winding — other windings exist and feel and cost differently
- 02Confirm 4/4 sizing before ordering; string length is not adjustable
- 03Expect several days of stretching and retuning before it holds pitch
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this include the other three strings?
No. This is the C string alone. The A, D and G are sold separately.
02What does the silver mean here?
It identifies the winding version of this C string. Spirocore Cs are offered in more than one winding, so match what your cello had.
03Will it fit a 3/4 cello?
No. This is cut for 4/4 scale. Order the matching size for your instrument.
04Why is a single string this expensive?
The low C is the longest and most heavily wound string on the cello, and it carries the highest material cost of the four.
