Detail 01
Phosphor bronze alloy
It provides the rich, natural tone associated with these acoustic strings.

Independent shopping perspective
Stringjoy Naturals 13–56 acoustic strings use phosphor bronze alloy for a rich, natural sound. Their uncoated surface retains natural texture under the fingers, rather than the slick feel described for coated strings. With hand-crafted construction and quality materials, the set is made to keep performing through heavy use. It makes sense where an acoustic guitar needs to cover both studio recording and stage performance with full, resonant output.
