Belcanto 3/4 Bass Long E (C ext.) - Chrome/Rope Core, Medium

The Thomastik-Infeld Belcanto 3/4 Bass Long E String is designed for double bassists using a C-extension setup who need the added string length without sacrificing response or tonal focus. This medium-tension Belcanto Orchestra string offers a dark, warm sound with reliable projection, making it a practical choice for orchestral bassists, students, teachers, and working players who need dependable low-register performance.

Built with a rope core and chrome winding, the Belcanto Long E speaks cleanly under the bow and supports a stable pitch center through extended rehearsals, services, and concert programs. Its flexible response helps the string feel secure without becoming overly stiff, while its natural pizzicato character gives bassists useful versatility for chamber music, jazz, and commercial playing. Thomastik-Infeld lists the BC64C extension string for 3/4 double bass with medium tension and a 104.0 cm / 40.9" vibrating string length.
