I own a CB-50 and it was designed as a CC instrument. It can be played in BBb if the included slides are used in the fifth valve and the valve is 'turned' so that it is always in the open position. I always play it in CC (actually I've never even tried it in BBb) and I think it is a wonderful horn.
