D’Addario EFT13 Flat Tops Phosphor Bronze Acoustic Guitar Strings

The EFT13 Flat Tops set combines the tone and tension of D’Addario’s best-selling EJ42 resophonic guitar strings with a smoother, polished surface for reduced string noise. Precision wound with phosphor bronze wrap wire over a hexagonal high-carbon steel core, these strings are then ground and polished to achieve a semi-flat finish. This process retains the warm, balanced tone and sustain of phosphor bronze while providing a smoother feel, making them excellent for recording and flat-picking. The medium gauge 16-56 set is optimized for resophonic guitars, delivering the ideal tension and tone for these instruments.
