D’Addario EXP23 Coated Phosphor Bronze Acoustic Guitar Strings, Baritone, 16-70

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.
