D'Addario EXP strings are created using advanced proprietary machinery. Starting with a micro-coated wrap wire that is precision drawn, EXP strings with NY Steel are then wound normally to maintain feel and tone. The only difference a player will notice is that the string lifespan is a minimum of 4 times longer.
D'Addario EXP strings with NY Steel deliver the natural, vibrant sound of regular phosphor bronze and 80/20 bronze acoustic strings with an unparalleled pitch stability. EXP strings not only last substantially longer, but they hold their tune better than any competitor strings.
