Evah Pirazzi Bass Strings have a core made from a modern synthetic multifilament fiber which is wound with chrome steel. The all-round string set: suitable arco and pizz alike. The sound is big, powerful, dark and well-rounded. Emphasized lower frequencies and outstanding resonant decay, exceptional projection, high torsional stiffness, short playing-in-time, very quick response and comfortable left-hand feeling, completely insensitive to changes in temperature and humidity.
