Pirastro Obligato Violin Strings
Pirastro Obligato has a composite core. Many strings of this type are bright and focused, but Obligato has a warm gut-like tone. The Chrome A is a brighter than the aluminum A. The Aluminum D is brighter than the Silver D. Obligato are made for small Violins, making them one of the few choices of professional quality strings for fractional-size instruments.
