The 540 model is one of the oldest in the Savarez arsenal. 

Basses are wound using the traditional method of the French string factory that began operating in the 18th century.

Savarez Alliance strings are made of carbon fiber. They are the result of years of development designed to meet the needs of musicians: a bright and uniform sound when switching between strings, accuracy in pitch, and the level of resistance of the string allows for smooth and agile playing.
