Detail 01
Single string, not a set
Only useful if the rest of your strings still have life. Mixing new and old changes the balance across the bass.

D'AddarioDZ613 Zyex 3/4 Bass Single A String Light
Independent shopping perspective
The Korena take
A single A string for 3/4 double bass, light gauge, from D'Addario's Zyex line. For replacing one string rather than buying a full set.
Strong match
Who this is for
- Replacing a broken or dead A string only
- 3/4 bass players already running Zyex strings
- Keeping a spare A in the case for gigs
Consider the trade-offs
When to look elsewhere
- Anyone needing a complete set — this is one string
- Bass sizes other than 3/4
- Players wanting heavier tension than light gauge
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
Zyex synthetic core
Synthetic core is warmer and more stable under temperature and humidity swings than plain steel.
Detail 03
Light gauge
Lower tension means an easier left hand and easier pizzicato, with less volume and pull than medium.
Detail 04
3/4 sizing
3/4 is the standard adult double bass size. A 1/2 or 4/4 instrument needs a different string length.
Detail 05
A string specifically
Second-from-lowest. Confirm which string you're replacing before ordering — the gauges are not interchangeable.
Final check
Know before you order
- 01One string only — no set, tools, or accessories included
- 02Match the gauge to your other strings or the balance will be uneven
- 03Synthetic core strings need several days to fully settle in
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is this one string or a whole set?
One string — the A.
02Will this fit a 1/2 size bass?
No. This is cut for 3/4 double bass. Other sizes need the length matched to the instrument.
03Can I mix this with medium gauge strings?
You can, but tension and feel will be uneven across the bass. Matching gauges across the set keeps response consistent.
04How long before it settles in?
Synthetic core strings stretch more than steel. Expect several days of retuning before the pitch holds steady.
