It is extremely rare for musicians and mathematics to be closely related, but this new series makes it a reality. The Balanced Tension XL series is D'Addario's solution to the problems found in traditional sets of strings. The gauges of standard sets, which have been loved for many years, were determined after decades of trial and error, with little logical basis behind them. As a result, there were significant variations in the tension of these sets, leading to perceived differences in "tightness" or "looseness" between strings. These tension variations consciously or unconsciously affected players' techniques. D'Addario has listed the tension of each string on its packaging for decades. More than ten years ago, they created a "Tension Guide" to disseminate information about string tension. This guide continues to be used to answer questions from users interested in string tension and the technical aspects of products. This guide led to hundreds of inquiries to D'Addario via email, social media, and online product forums, asking if something could be done about these tension variations. In response, D'Addario's engineering team combined music and mathematics to create the ultimate solution: the "Balanced Tension XL series."

This is a set of strings with balanced tension across each string, achieved by slightly altering the gauges of some strings.
You can experience an exquisite tension balance that is unique to each string when fretting chords or performing string bends.
Gauges: 40, 55, 70, 95
