Evah Pirazzi Bass Strings Orchestra has a modern synthetic core wound with chrome steel. This all-around string set is suitable with a bow and pizzicato alike. The sound is big, powerful, dark, and well-rounded. These strings emphasize lower frequencies and outstanding resonant decay. With exceptional projection, high torsional stiffness, short playing-in-time, very quick response, and comfortable left-hand feeling, these strings are a great choice. They also offer exceptional tuning stability, completely insensitive to changes in temperature and humidity.
