Designed in collaboration with clarinet great Larry Combs, the Opus II represents the next logical step in the evolution of the Leblanc artist line. This remarkable clarinet offers the same rich, expressive tone and ease of play as the original Opus model, but with the added advantage of a revolutionary key-work design. Its gracefully sculpted keys lie perfectly under the fingers for increased dexterity and endurance, and numerous enhancements.
