Larsen Virtuoso violin E strings have a moderate tension capable of rich, nuanced sound with exceptional volume. Available in medium or heavy gauges, Virtuoso E strings are well suited for warm- to neutral- sounding instruments. The heavy gauge allows for a focused, soloistic sound with higher bow resistance, while the medium gauge offers great response, playability and sound modulation. Larsen Virtuoso violin E strings are made of solid unwound unique carbon steel, with a ball or loop end.
