Precision are by no means a new invention and are based on the original ideology of Dr. Thomastik and Otto Infeld. They have been produced in consistent quality since 1920, constantly being updated to incorporate the latest technical findings and our wealth of musical experience. Precision strings are ideal for students, ensemble players and folk musicians. This standard model has remained popular to this day, not only because of its price range but its long playing life. It should be noted that the bass strings are not suited to pizzicato playing. For the player who wishes to experiment, Thomastik-Infeld recommends the e2-mi2 range, where all the violin E strings we produce can be supplied individually. New gauges and grades of tension have been included for even greater variety.
