The Frirsz cello tailpiece will transform your instrument by enhancing projection, balance, and response. Wolf tones are tremendously reduced, and on most cellos, completely eliminated. The cut-away design lightens the tailpiece and opens up the sound of the cello. This tailpiece also features modular integrated fine tuners that are interchangeable with traditional "keyhole" type of string attachment inserts, so it can be configured to your preferred set-up. With performance improvements you will hear and feel, and features that enable a personalized configuration, this innovative tailpiece really delivers. We guarantee it.
