D'Addario Helicore Orchestral Bass Ext. C String

Helicore Orchestral bass strings are multi-stranded steel core strings that produce a warm tone quality with excellent bow response. The groundbreaking core design produces strings that are very easy to play. Damping is optimized for arco use, but they also work well for pizzicato applications where a very warm, less-sustaining sound is desired.

• Stranded steel core, nickel winding
  
• Clear and focused articulation
• Optimized for arco use
  
• Short break-in time
• All D'Addario strings are designed, engineered, and manufactured in the USA
