EFT13 Flat Top strings combine the tone and tension of D'Addario's best selling EJ42 Resophonic guitar set with a smoother, polished surface for reduced string noise. 

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.
