About GAMMA Sports

Bringing passion and innovation to racquet sports

GAMMA Sports is a family-owned business with a 40-year history of developing innovative products that advance racquet sports for players of all levels.

The GAMMA History

In 1974 Dr. Harry Ferrari lost a tennis match due to inferior synthetic gut strings. Ferrari, a nuclear engineer and avid tennis player, became determined to develop a better tennis string. Dr. Ferrari’s experiments radically improved the strings’ performance, and ultimately led to the creation of the patented GAMMA irradiation process. With that, GAMMA Gut was born, a string technology that provided players with greater power, feel and control. In 1977 the United States Racquet Stringer’s Association rated GAMMA Gut the #1 string for the first time. This winning streak would go unbroken for 23 straight years!
