D'Addario H510 Helicore 1/2 Size Cello String are justifiably popular for offering warm, rich sound that's remarkably similar to gut or synthetic core strings. Unlike gut, however, Helicore strings' all-metal construction renders them impervious to fluctuations in humidity and temperature.
D'Addario Helicore strings have a multi-strand high-carbon steel core for flexible response and range. The core is overlaid with exotic alloy windings that provide extremely quick bow response and outstanding projection. The end result is a versatile cello string with very long playing life that is extremely stable under all playing conditions.
