The Dean Markley HELIX HD 2080 Acoustic XL strings are extra light guitar strings that will give your music a sound like no other. It took over a year and many trials for the Dean Markley team to find just the precise elliptical shape for the winding wire that makes up the patent-pending, Hyper-Elliptical Winding process of the Helix HD acoustic guitar strings. This shape then had to be paired with the correct winding process that would produce these outstanding results—the maximum mass for the acoustic guitar string's diameter that still maintained the string's vibrancy.
The Hyper-Elliptical Winding process results in an increased number of wraps along the length of the string. This increases the mass of your acoustic guitar string, without changing its diameter or material.
More mass makes the Dean Markley HELIX 2080 guitar strings have a fuller tone; more windings give a smoother feel as well as a brighter, more resonant tone. This provides a smoothness and performance unrivaled by conventional strings.
When you press and strum a normal wrap wire, your fingers experience resistance as they go down into each depression between the wraps. With the Dean Marley HELIX HD guitar strings you'll experience smoothness. These less coarse wrappings let your fingers glide more easily and smoothly along the surface of the wrap wire.
Made of 80% copper, and 20% zinc, these Dean Markley acoustic guitar strings are made of a true brass alloy—well-balanced and durable for loud, rich sound that is exceptionally long-lasting. Helix HD's unique Hyper-Elliptical Winding process adds more projection and tone than other strings of the same gauges, and reduces corrosion and finger noise on the surface of the string.
