Adamas Lute Strings with Ball End from MusicLand. These strings offer exceptional quality, warm and rich sound, and a very soft feel in the hand. Phosphor Bronze strings are the number one choice for the best acoustic tone. The color in the windings has a "reddish" hue that resembles copper. They produce a "full" and "warm" sound. For instruments used acoustically or amplified with a microphone, piezo, or sensors (pickups), Phosphor Bronze is the best choice. Their full and sweet sound, along with the softer feel in the hand, are advantages that make them ideal especially for long playing sessions.
