Pirastro Obligato Violin String Set, 4/4 Medium - Ball-End / Steel

Pirastro Obligato Violin String Set, 4/4 Medium

The Pirastro Obligato Violin String Set offers three 4/4 medium configurations: steel E with loop end, steel E with ball end, or gold-plated chrome steel E with ball end. Each includes synthetic-core A, D, and G strings with aluminum, silver, and silver windings respectively. All lower strings have ball ends.

For students, orchestral musicians, and chamber players choosing full size replacement strings, these options let you match the E-string material and attachment to your setup. Select a steel E violin set with the fitting your fine tuner accepts, or choose the gold-plated ball-end configuration. Every selection supplies all four notes together for a complete replacement.

The A, D, and G use synthetic multifilament cores, formed from multiple fibers beneath their metal windings. Pirastro identifies the gold-plated E material as Goldchrome and distinguishes it from the regular steel option. Check your E-string fitting before ordering, since the loop designation applies only to that string. Manufacturer article numbers identify each configuration, and all three sets use envelope packaging.
