Innovation & technology
The EJ string series from D'Addario not only stands for outstanding sound, but also for state-of-the-art technologies and innovative manufacturing processes. Each string benefits from D'Addario's advanced wire-drawing technology, where the wire is precisely drawn to exact specifications to ensure maximum durability and performance. The hexagonal high carbon steel core, also known as Hex-Core, provides improved tuning stability and allows for even winding, which optimizes intonation and playing comfort. String winding technology ensures that the winding wire is wound tightly and evenly around the core, resulting in consistently high quality and a consistent sound. Thanks to these technologies, you can rely on D'Addario strings whether you are on stage, in the studio or practicing at home.

Wire Drawing
D'Addario's in-house wire drawing facilities produce musical instrument wire to exact specifications. Control over materials, equipment and quality enables the string manufacturer to deliver high performance products.

Hex-Core
Hex Core technology, where the winding wire wraps around the core, provides superior dimensional stability and precise intonation.

String Winding
The digitally controlled string winding systems guarantee productivity, accuracy and consistency. They ensure that the winding wire is wound tightly and evenly around the core. The ball ends are also colored to reduce packaging material.
