Virtuoso Series mouthpieces are made from Bradford Behn’s proprietary rod rubber. Behn Proprietary Rod Rubber is the exquisite, resonant material used for clarinet and saxophone mouthpieces produced in France during the 1920’s golden era. Features of this material coupled with our designs include a uniquely rich sound, unmatched integrity and clarity of sound at all dynamics, and flexibility for the discerning artist to access different colors and timbres. Dahlke Virtuoso Series mouthpieces are the only saxophone mouthpieces in the world made from this gorgeous material.
