For Classical Guitars, we recommend Ernie Ball Earthwood Folk Nylon, Clear & Gold Ball End strings. The plain strings are made of a solid nylon filament - First, second and third strings are Clear, ball end (similar to, but not the same as, the nylon used for fishing line). Gold ball end fourth, fifth, and sixth wound strings are made of 80/20 bronze alloy wrapped around a nylon floss core.
