D’Addario EJ17 acoustic guitar strings are designed with heavier tension, producing a bolder, more resonant tone that can handle the demands of heavy strumming and flat-picking.

These strings are precision-wound with corrosion-resistant phosphor bronze onto a carefully drawn, hexagonal high-carbon steel core. This construction ensures a long-lasting, bright tone with excellent intonation.

Introduced by D’Addario in 1974, phosphor bronze has since become synonymous with a warm, bright, and well-balanced acoustic guitar sound.
