New Improved D'Addario Helicore Bass Strings are now available in all three brands, Arco, Pizzicato, and Hybrid. Orchestra players, jazz pros, students, and their teachers like the even tone across all four strings, as well as the easy 'start' that are the hallmarks of Helicore Bass.

Helicore Hybrid has also been improved by removing the damping layer to allow much greater volume and sustain while the arco response has been warmed up by chaning the core wire. Color wrap in the tailpiece is green with a golden spiral. Again, we are most pleased that the original formula Hybrid Bass String has been improved.

Helicore Medium Gauge Bass Strings are the most adaptable and will service the greatest number of upright basses. A solid blue band at the end of the color silk denotes Medium Tension.
