Savarez - 505J Filé Métal Argenté 5e Blue

The fifth string is the one that sets the sound floor of a classical guitar. Its bass must descend without mud, remain articulated under the thumb's bow, and hold its height throughout the length of the neck. The 505J's high-crystal nylon core meets this requirement with an ordered internal structure that converts every vibration into a clean sound - the resulting extended sustain holds the note without the low end being diluted by parasitic harmonics.

The silver thread on the unground surface of the core ensures that the winding adheres to the core wire: under the high tension and repeated stresses of playing, the winding remains firmly attached to its support. Laser diameter control checks the regularity of the wire at every centimetre to eliminate bulges that would create dull spots on the vibrating length. The great flexibility of this assembly reduces the pressure needed in the left hand, and the attack response remains clear even on this low string, with an increased sound volume that carries the low A effortlessly through the whole stop.

The 505J covers three classical guitar restocking contexts: Corum basses, New Cristal trebles and Savarez Alliance Fluorocarbon. Sold as a single string, its blue identification simplifies targeted replacement, and its high tension matches sets whose general architecture pulls towards the top of the tension spectrum.
