The D'Addario EJ38 Phosphor Bronze strings are the most popular choice for 12-string acoustic guitars, offering a light 10-47 gauge that perfectly balances rich volume with comfortable playability. Designed to handle the high tension of a 12-string setup without sacrificing ease of fretting, this set provides the warm, bright, and well-balanced tonal signature that has made D'Addario's Phosphor Bronze an industry standard since 1974. Precision-wound with corrosion-resistant phosphor bronze over a high-carbon steel hex core, the EJ38s deliver exceptional intonation and a lush, shimmering harmonic profile that enhances the natural chorus-like resonance of any 12-string acoustic instrument.
