Trebles strings are the result of the major and definitely relevant innovation in guitar strings since many centuries.
Savarez took profit of the discovery of a new synthetic material early in the 20th century : the nylon. It definitely took the place of the gut which had been used on musical baroque instruments and on classical guitars since their origin.
Savarez brought two major improvements never offered to the musicians before and that have completely changed the world of guitar:
- The rectifying technology which enables to get strings perfect in tune and being perfectly cylindrical.
- The possibility to offer strings with accurate tensions as well as a choice of tensions.
