Detail 01
Single string, not a set
You get the high C only. Buying a full set separately is the cheaper path if all four or five are due.

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
4/4 size
Cut for full-size double bass scale. On a 3/4 bass the winding may not land correctly at the nut or tailpiece.
Detail 03
Spirocore line
Mixing string lines across a bass gives uneven tension and response. Match this to Spirocore neighbors.
Detail 04
High C tuning
Sits above the G string on a five-string or replaces a low E on a four-string tuned in the upper range.
Final check
Know before you order
- 01This is one string, not a complete set
- 02Confirm your bass is 4/4 — 3/4 is the more common size
- 03Your bridge and nut slots may need widening or refiling for a C
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is this a full set of bass strings?
No. This is the high C string on its own.
02Will this fit a 3/4 bass?
It's cut for 4/4 scale. On a 3/4 bass the speaking length and winding transitions likely won't line up correctly.
03Do I need a five-string bass to use this?
Typically yes — a high C sits above the G. Some players use it on a four-string tuned in an extended upper range.
04Can I mix this with other string brands?
You can, but tension and feel will differ across the bass. Matching it to other Spirocore strings keeps the response even.
