La Bella's Phosphor Bronze sets are made with our exclusively formulated bronze and tin alloy, producing a brighter tone and longer string life than any other phosphor bronze set on the market. Since its introduction in the 1970s, the Phosphor Bronze Series has become our most popular acoustic set for all genres of music.
The strings are made in the USA with American wire.
