Gold plated Josef Klier 3B contrabass trombone mouthpiece. This is probably the smallest contra mouthpiece on the market. It would be a great piece for the bass trombonist wanting a large mouthpiece. I know there aren’t that many contra players out there, but, if you are one and are looking for a quality smaller mouthpiece, this is it. This was only played maybe two times to compare to my Ferguson piece. This runs $185 new… my price is $75 or $85 shipped.
