Each treble string (cantini) in the Pro-Arte EJ45 set undergoes an advanced inspection with a digital laser that performs 200 measurements per inch. This process guarantees that the strings have perfectly uniform diameter and tension along their entire length. The result is flawless intonation and stable tuning, allowing you to play with confidence on every fret of the fingerboard.

Normal Tension is the most popular choice, as it offers an extremely comfortable feel for the fingers without tiring the hand. It allows the guitar to "breathe," producing a warm and sweet sound with rich harmonics. It is the ideal tension for learning fingerstyle techniques, providing the necessary dynamic response to express every musical detail.

The bass strings of the EJ45 feature a multi-filament nylon core, which is wound with silver-plated copper. This combination provides deep, full bass with excellent sustain and the ideal resistance for the right hand. The quality of the materials ensures that the sound remains bright and lively for a long time, even with daily practice.
