Pirastro Flexocor Orchestra Tuning Bass Strings
The Pirastro Flexocore (Orchestral) Bass Strings' core material is a high-tensile rope made from carbon steel which is wound with chrome steel.
This is an outstanding set for arco, which can withstand a powerful and heavy bowing arm. They produce a brilliant sound with a short sustain and a powerful sound with great projection and big tonal volume.
They are instantly playable and absolutely stable, quickly responding, slightly quicker than Original Flat-Chrome.
