D'Addario has been crafting high-quality guitar strings since the early 70's, starting from a 2,000 square foot storefront in Long Island and then expanding to become a global leader. With an emphasis of quality strings for all different instruments, they're known for their rich tone and reliability. Ranging from the Pro Arte series for classical experience, or the EXL110 and NYXL offering balanced tension, tone, and durability for electric guitarists. Whether you need XL strings for an extra punch or replacement strings that last longer, D'Addario's craft and experience has stood the test of time for players across the world.
