The D'Addario EJ16 Phosphor Bronze strings are the industry standard for acoustic guitarists, offering a light 12-53 gauge that perfectly balances rich volume with comfortable playability. Since D'Addario pioneered the use of this alloy in 1974, these strings have become world-renowned for their warm, bright, and well-balanced tonal signature that suits a wide variety of playing styles. Precision-wound with corrosion-resistant phosphor bronze over a high-carbon steel hex core, the EJ16s provide exceptional intonation and a long-lasting, vibrant shimmer that enhances the natural voice of any acoustic instrument.
