I saw this at a convention the other day in Lancaster, PA while I was at All-State. It’s a Buffet Prestige bass clarinet BC1193………. This is the most beautiful instrument I’ve ever seen. It’s wooden, has a low C and D extension, an Ab lever, and an Eb lever. I almost fainted when the guy told me it costs $9500… I wish I brought my mouthpiece with me to play it but I only had my contrabass mouthpiece with me.
