Phosphor bronze wound strings were introduced in the early 1970s and have become the most popular acoustic string. Phosphor bronze wire consists of approximately 92% copper, 7% zinc, and 1% phosphorus. Phosphor bronze produces beautiful high and low notes with pleasant, subtle overtones. Phosphorus is used to reduce tarnish and corrosion.

Born from the biggest breakthrough in string innovation, XS Phosphor Bronze strings have the longest lifespan of any D'Addario acoustic guitar string. The XS coating gives the warm, well-balanced phosphor bronze strings maximum lifespan, with an unusually smooth feel. Made with a NY steel core, phosphor bronze wrap wire, and Fusion Twist Technology, XS Coated acoustic guitar strings have unparalleled breaking strength and tuning stability, in addition to their significantly longer lifespan.

When it comes to strings, it's all about tension. While gauge is simply the measurement of the string's diameter, a string's tension determines its relative volume to the other strings (EQ). String tension is determined by the core-to-wrap ratio, which can vary significantly between manufacturers. This can lead to differences of several pounds between brands and inconsistent EQ within a given set.

Santa Cruz strings are designed to do what others can't: apply the precise tension to each individual string to create the correct pressure. These calculated tensions determine the optimal relative volume between strings, or EQ, for your instrument. Santa Cruz strings require precise core-to-wound ratios and meticulous fit and finish to achieve unprecedented tolerances of half a thousandth of an inch. This precisely controls the tension/volume of each string to the precise EQ your guitar is designed for. State-of-the-art metallurgy and micro-coating ensure long life by preventing corrosive moisture from coming into contact with the core of these nickel- and lead-free strings.

D'Addario's most popular acoustic bass, the EPBB170, offers a rich, deep, and projecting tone.

Phosphor bronze was introduced into string production by D'Addario in 1974 and has become synonymous with warm, bright, and well-balanced acoustic tone. D'Addario Phosphor Bronze strings are precision wound with corrosion-resistant phosphor bronze onto a carefully drawn, hexagonal, high-carbon steel core. The result is a long-lasting, bright tone with excellent intonation.

The EJ38, D'Addario's most popular 12-string set, offers the ideal balance of volume, projection, and comfortable playability. Designed for all makes and models of 12-string acoustic guitars.

Phosphor bronze was introduced to D'Addario strings in 1974 and has become synonymous with warm, bright, and well-balanced acoustic tone. D'Addario Phosphor Bronze strings are precision wound with corrosion-resistant phosphor bronze onto a carefully drawn, hexagonal, high-carbon steel core. The result is a long-lasting, bright tone with excellent intonation.

The EJ26 strings, designated Custom Light, are an original D'Addario hybrid gauge and a comfortable compromise for players who want the depth and projection of the light set's lower strings, but slightly less tension on the higher strings for easy bending.

Phosphor bronze was introduced to D'Addario strings in 1974 and has become synonymous with warm, bright, and well-balanced acoustic tone. D'Addario Phosphor Bronze strings are precision wound with corrosion-resistant phosphor bronze onto a carefully drawn, hexagonal, high-carbon steel core. The result is a long-lasting, bright tone with excellent intonation.

EJ17s offer a heavier tension, resulting in a bolder, more resonant acoustic tone with greater resistance for heavy strumming and flat-picking.
