Savarez 500AJ Alliance Corum High Tension Classical Guitar Strings Experience the magic of COMPOSITE strings Experience the breath taking difference with high tension composite strings. Savarez 500AJ classical guitar strings utilize KF Alliance material technology to produce a new generation of classical strings, with impressive performance and endurance. Carbon composite KF Alliance treble strings have higher tensile strength, higher density, and longer life than nylon, and are more sensitive and expressive. Their tone is clear and ringing, with strong volume and projection. The bass strings are silver-plated copper wound, over Savarez's KF Alliance composite fiber cores. KF Alliance cores are more flexible than regular nylon filaments, allowing these high tension strings to feel and play more like normal tension strings. The bass strings have silver plated windings over Corum cores. This allows the guitarist to have more flexibility and creative control over his tone and projection, because the strings are so sensitive to the human input. The set has a clean sound, with longer sustain and more volume than standard strings, with a dramatic increase in sensitivity, compared to standard classical guitar strings. Savarez Alliance Corums are clearly an advanced classical guitar string, with outstanding playability and sonic characteristics. Try a set and see for yourself.
