Sampras used one racket type, the Wilson Pro Staff Original, for his entire professional career—a racket first introduced in 1983. He played with Babolat natural gut, with all his rackets re-strung before each match (used or not) at 75 lbs tension (more or less, depending on conditions). His rackets had weight added to bring them close to 400 g, but the frame proper was a production model manufactured at a Wilson factory on the Caribbean island of St. Vincent. The handles were custom-built.
