- School and rental basses that get heavy use
- Players mixing bowed and plucked work on one setup

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
Full-size bass only. Fractional basses have shorter string lengths and need their own set.
Detail 03
Rope-stranded core
More flexible than solid steel. Easier under the bow and less stiff under the left hand.
Detail 04
Full four-string set
Matched tension across all strings, so the bridge load and feel stay even string to string.
Detail 05
$314.95
Bass strings are long and expensive to make. Expect years of service rather than months.
Final check
Know before you order
- 01Confirm full-size 4/4 bass before ordering — fractional sizes need different string lengths
- 02Budget for a luthier if the bridge or nut needs recutting for these gauges
- 03Replace one string at a time so the soundpost stays put
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these work for both bowing and pizzicato?
Yes. Steel core with rope stranding handles arco without excessive stiffness while still giving clear pizzicato attack.
02Do these fit a 3/4 bass?
No. This set is for 4/4 full-size basses. Most orchestral basses sold as standard are actually 3/4 — measure your string length first.
03How long will they last?
Steel core bass strings commonly last years under regular playing, far longer than gut. Replace when the winding flattens or pitch stability drops.
04Is this the full set?
Yes, all four strings for one bass.
