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.

Solo Tuning Arco is the thinnest gauge of all and can be tuned to A-E-B-F#. Color wrap in the tailpiece is brown silk with a golden spiral. There is no additional color band that denotes tension.
