The D'Addario EJ19 Phosphor Bronze strings are a specialized "Bluegrass" hybrid set that combines the playability of light-gauge high strings with the heavy-duty projection of medium-gauge low strings. Featuring a unique 12-56 gauge profile, this set allows for comfortable lead work and easy bending on the trebles while providing a thick, punchy bass response for powerful rhythmic strumming. The phosphor bronze winding delivers the warm, harmonically rich, and well-balanced tone that has defined the D'Addario acoustic sound since 1974, ensuring long-lasting vibrancy and excellent intonation. Precision-wound on a high-carbon steel hex core, the EJ19s are the perfect choice for players who want a "best of both worlds" setup that can drive a dreadnought’s low end without the finger fatigue of a full medium set.
