By combining the traditional tailpiece with four built-in fine tuners, Otto Infeld created a tuning system which has remained unsurpassed to the present day as the solution for the problem of fine tuning. The elegant main body of the tailpiece is produced in modern pressure diecasting. The fine-tuning screws can be supplied in black or gold. Our tail clinch wires are produced in steel for all instruments, while violinists have the extra choice of a tail clinch wire in nylon for ease of fitting. Our fine tuners are optimized in size and weight for Thomastik- Infeld strings. The Infeld tailpiece allows the whole length of the string to vibrate freely, without the need for an additional ridge between tuner and bridge which could weaken the ball end and hamper resonance.
