Classical guitar strings are designed for players seeking greater volume, projection, and a firmer feel under their fingers. Part of the Pro-Arte series, these strings offer excellent durability and responsiveness. The bass strings (fourth to sixth) are wound with silver-plated copper, which provides a rich, bright tone with impressive sustain and clarity. The treble strings (first to third) are precision-made from clear nylon, delivering a smooth and articulate sound.

Hard tension strings like the EJ46 require more pressure to play, making them ideal for guitarists who prefer a tighter, more controlled feel. They are well-suited for concert performances, projecting a fuller, more robust sound without sacrificing tonal precision. Additionally, these strings maintain excellent intonation and are favored for their consistency across different playing styles, particularly in classical, flamenco, and fingerstyle genres.
