D'Addario EFT17 Flat Top Medium Acoustic Guitar Strings are phosphor bronze strings polished smooth. This produces a smooth, flattened playing surface, but does not sacrifice the warm tone and sustain associated with phosphor bronze strings. Flat Tops are excellent for recording and greatly reduce finger noise.

D'Addario is the world's largest manufacturer of strings for musical instruments. Many top guitarists won't play any other brand. Regardless of your playing style, D'Addario has a set of strings that's right for your acoustic guitar.
