D'Add EJ39, 12-52

The D'Addario EJ39 Phosphor Bronze strings are a medium-gauge set specifically designed for 12-string acoustic guitars, featuring a 12-52 gauge profile. As a heavier alternative to the standard light sets, the EJ39s provide maximum volume and a powerful, driving resonance that is ideal for heavy strumming and professional projection. These strings utilize D'Addario's legendary phosphor bronze alloy, delivering a warm, rich, and harmonically complex tone that beautifully complements the natural "chorus" effect of a 12-string instrument. Precision-wound on a high-carbon steel hex core, they offer the structural integrity and tuning stability required to manage the high tension of a 12-string setup while maintaining a long-lasting, vibrant shimmer.
