Detail 01
Single A string, not a set
You get one string. Mixing brands across a bass gives uneven feel and volume string to string.

ThomastikSpirocore 3/4 Size Double Bass Strings 3/4 Size A String
Independent shopping perspective
The Korena take
A single A string for 3/4 size double bass. For players replacing one string rather than buying a full set.
Strong match
Who this is for
- Replacing a broken or dead A on a 3/4 bass
- Keeping a spare A in the case
- Staying matched to an existing Spirocore set
Consider the trade-offs
When to look elsewhere
- Anyone needing a complete set — this is one string
- Bass guitar players; this is upright double bass
- Basses other than 3/4 size without checking string length
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
3/4 size
Sized to the most common full-size-in-practice upright. A 1/2 or 4/4 bass needs different length.
Detail 03
Double bass, not bass guitar
Upright string, far longer and under much higher tension than any electric bass string.
Detail 04
Spirocore line
Staying within one line keeps tension and response consistent with the other three strings you already have.
Detail 05
Price per string
Upright strings cost roughly this much each, so replacing all four is a several-hundred-dollar decision.
Final check
Know before you order
- 01Confirm your bass is 3/4 size before ordering
- 02One string only — D, G and E sold separately
- 03New upright strings settle over days; expect repeated retuning
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is this a full set?
No. This is the A string alone. The E, D and G strings are separate purchases.
02Will this fit my bass guitar?
No. It is made for upright double bass, not electric or acoustic bass guitar.
03Can I use it on a 4/4 or 1/2 size bass?
It is cut for 3/4 size. Other sizes need the matching string length for that instrument.
04Can I mix this with strings from another brand?
You can, but tension and response will differ across strings. Matching the rest of your set is more consistent.
