Until the mid-20th century all treble guitar strings were made in gut, a material that had been used for thousand of years and that combines good promptness of attack and excellent performances. A fundamental aim of Aquila's research has therefore been to design a new synthetic product having the same acoustic properties as gut, but without its typical defects (high cost, short lifetime, high instability under moisture changes). Their New Nylgut has precisely all these good qualities without all these defects.
Its features include promptness of attack, excellent performances and a truly remarkable stability of intonation under moisture changes. The Alabastro basses, wound with high quality- silver-plated copper, consist of a New Nylgut multifilament core that ensures not only a high resistance to tensile stress but also a low absorption of both atmospheric humidity and sweat.
