A TRUE BREAKTHROUGH Nicholas Frirsz, a fifth generation Master Luthier, has designed and patented a very innovative tailpiece that dramatically improves the projection, balance, and sensitivity of bowed string instruments. The tailpiece creates this transformation by optimizing the harmonics in the after-length, and redistributing the down force on the bridge to bring out the best qualities of your instrument • Wolf tones are no longer a problem as this tailpiece virtually eliminates them. This design has been thoroughly tested and proven. It works, and we back our claims with a money back guarantee. Frirsz tailpieces are now available in a wide variety of materials, colors, and price points and are all made in the USA to exacting standards. Breaking The Sound Barrier. Contact Us for more.
