These are the most durable guitar strings of all time! D'Addario NYXL strings do not require extra stretching after installation, hold their tuning significantly longer, and provide a higher output at the same time. The new high-carbon steel alloy allows for faster tuning of the guitar with more punch, crunch, and bite. In the future, you'll be heard even better. Get ready for an encore!

The newly developed, tear-resistant high-carbon steel core and new steel alloy provide more output and improved tuning stability. Higher magnetic permeability leads to a performance boost in the frequency range of 2 to 5 kHz. Developed, perfected, and manufactured by D'Addario in New York.
