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 Arco has been reformulated to have a richer, more complex tone. A bit of added mass creates more volume and makes the string more lively for larger orchestra basses. Overall the tone is more robust and more complex. Arco comes in three gauges, Light, Medium, and Heavy. Color wrap in the tailpiece is blue silk with a golden spiral.

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.
