These D'Addario EJ17 phosphor bronze strings are built for guitarists who demand power and durability from their acoustic sound. The three-pack features medium gauge 13-56 strings with a high-carbon steel hex core that provides exceptional strength and stability under tension.
The heavier gauge construction creates increased tension across the fretboard, resulting in a bold and resonant tonal character that cuts through any mix. These strings are particularly well-suited to aggressive strumming patterns and flat-picking techniques, maintaining their tuning stability and tonal integrity even under demanding playing conditions.
Each set comes in corrosion-resistant packaging that protects the phosphor bronze windings from environmental damage, ensuring the strings maintain their quality and tone from package to performance. This protection helps extend string life and preserves the bright, warm characteristics that make phosphor bronze a favourite among acoustic players.
