Noise Free - La Bella 413P Studio Professional Recording Classical guitar strings are truly a unique development. 413P's have high-density nylon treble strings and polished wound bass strings. This is the world's first noise free classical string, thanks to La Bella's stone grinding process, which eliminates finger noise when shifting positions or playing glissando. They also have a full and even tone, with remarkable presence and sensitivity to the player's most delicate inflections. 413Ps are the preferred choice of classical guitar artists, for both concert performances and studio recording. Chet Atkins used La Bella 413P strings on his classical guitar recordings, because they gave him the full tonal spectrum he demanded, and were exceptionally quiet under his fingers. La Bella 413P's are made for the recording studio, but their advantages can be extended to any setting where perfectly clear and clean notes are desired. Chet Atkins played La Bella 413P's for his classical and nylon string guitar pieces, even back in the 70's. See Review: Chet's Favorite Classical Strings Benefits: Crystal clear trebles and silky smooth, stone ground bass strings minimize finger noise, and blend smoothly for uniform string to string tone and volume. Perfectly matched string diameters and string tensions for sensitive classical guitars, La Bella 413P's reward you with hours of enjoyment and satisfaction. The "tarnish proof" finish of the wound strings lasts an exceptionally long time, keeping your strings looking as good as they sound. In Stock.
