5/4 BBb and CC first samples from China Richard Barth on Wed, 06/06/2012 - 12:37 comments I had a nice trip to Columbus and Buffalo showing the new samples of the 4/4 (5/4?) BBb and CC. Tony Zilincik met me at Buckeye Brass where he and his student Gretchen tried out the J-844LQ CC tuba. Gretchen ordered the sample. Then off to Buffalo.
