Plain strings are made of specially tempered, tin-plated, high-carbon steel, producing a well-balanced tone, and have a patented winding of bronze wire, tightly wrapped around the lock twist of the ball end. Wound strings are made from nickel plated steel wire wrapped around a hex-shaped steel core wire. Strings are precisely manufactured to the highest standards and most exacting specifications to ensure consistency, long life and optimum performance. Gauges: .008, .011, .014, .022w, .030, .038.
