D'Addario EFT13 Flat Tops Phosphor Bronze Acoustic Medium Resophonic Guitar Strings 16-56

D'Addario EFT13 Flat Tops are a medium-gauge phosphor bronze string set specifically designed for resophonic guitars, combining the warmth and balance of phosphor bronze with a smoother surface that significantly reduces finger and slide noise.

Unlike conventional roundwound acoustic strings, the wound strings are precision ground and polished after winding to create D'Addario's semi-flat Flat Tops profile. This retains much of the character and harmonic content of phosphor bronze while providing a smoother feel and quieter movement across the strings, making the set particularly well suited to slide playing and recording.

The strings use a high-carbon steel hex core with phosphor bronze wrap wire and are manufactured in the USA at D'Addario's New York facility.
