Detail 01
Medium gauge
More tension than the light version of the same set. Stiffer under the fingers, more resistance and more drive into the instrument.

D'AddarioDZ610 Zyex 3/4 Bass String Set Medium
Independent shopping perspective
The Korena take
Medium-gauge Zyex set for 3/4 upright bass. The higher-tension option for players who want more push behind each note.
Strong match
Who this is for
- 3/4 upright players who want a firmer, more resistant feel
- Arco work where higher tension helps the bow grab
- Players whose current set feels loose or floppy
Consider the trade-offs
When to look elsewhere
- Bass guitar — these are orchestral upright strings, wrong scale entirely
- Smaller student basses; the string lengths are cut for 3/4
- Players with left-hand fatigue who need lower tension
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
The standard adult upright size. Won't fit a 1/2, 1/4, or 7/8 bass without length problems.
Detail 03
Full set, not singles
All four strings change together, so tension across the bridge stays balanced instead of mismatched.
Detail 04
Zyex line
D'Addario's synthetic-core family rather than plain steel, so the feel under the hand differs from a steel orchestral set.
Detail 05
Price near $235
Upright strings are a yearly-scale purchase, not a routine one. Plan the change rather than doing it on impulse.
Final check
Know before you order
- 01Swap one string at a time to keep the soundpost and bridge in place
- 02Set only — no rosin, no tools, no bridge or tailpiece hardware
- 03Higher tension may shift bridge lean; check it after the change
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Medium or light?
Medium pushes back harder and drives the bass more; light is easier on the left hand. Same set otherwise — pick by feel, not tone.
02Can I put these on a bass guitar?
No. These are 3/4 upright bass strings. A bass guitar takes a completely different string.
03Will medium gauge damage my bass?
Higher tension puts more load on the top and bridge. If your bass is old or lightly built, have a luthier look before switching up.
04Do I need to change all four at once?
You don't have to, but replacing one at a time keeps tension on the bridge and soundpost while you work through the set.
