As a half round phosphor bronze acoustic guitar set, Flat Tops are designed to significantly reduce unwanted finger noise. Combining tried-and-true phosphor bronze tone with a smoother feel and quieter playing experience, they’re excellent for recording—and slide guitar playing. Flat Tops are made with a high carbon steel core and phosphor bronze wrap wire, which is then precision ground and polished, leaving behind a semi-flat string with a smooth feel and beautifully balanced tone. 13-56 Medium gauge strings provides maximum volume and projection, with more tension and resistance.

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.
