Kronwalt is the result of close collaboration between two major bassoon-makers. Walter, winner of the German Musicians Instrument Prize in 1994 and 2002, supplies the seasoned mountain maple and creates the bore. Wolf, a specialist in both historical and modern bassoons, provides their innovative and uniquely designed keywork.

Wolf and Walter have collaborated with instrument innovator Benedikt Eppelsheim to introduce the Kronwalt contrabassoon. This newly designed instrument combines the traditional sound aesthetics of a contrabassoon with new key innovations to make an instrument that is not only extremely well-constructed, but has beautiful tone and an ergonomic key system.
