The Korena take
The San Francisco 10K Blue RR is a blue, RR-facing bass clarinet mouthpiece in the Clark W Fobes 10K line. It uses marbled blue material, which the maker identifies as contributing added brilliance. The design brings together vintage-mouthpiece elements and Fobes adaptations, with computer milling from solid German rubber rod stock. Extensive hand finishing and play testing are part of each mouthpiece, with response, resonance and tonal character named as the intended results. The RR facing makes this a clearly defined 10K Blue option.
