EFT16 is a light gauge set of strings for acoustic guitar, ideal for reduction of unwanted finger noise or for slide playing. Flat Top strings are precision ground, producing a smooth, flattened playing surface, without sacrificing tone and sustain associated with round wound Phosphor Bronze strings.
D'Addario Flat Tops are round wound, then precision ground, leaving the outer surface smooth and "semi-flat." This produces a smooth, flattened playing surface, but does not sacrifice the superb tone and sustain associated with phosphor bronze strings. Flat Tops greatly reduce finger noise and are excellent for recording and flat-picking.
