Thank you for viewing. This is a #1 bocal for bassoon. The brand is Takeda Bassoon, and it was originally included with the soloist model (model 4) that the seller purchased new. It was used for about two and a half years and has no dents or cracks. The cork has come off, but there are no air leaks, so it does not affect playing. (We recommend having the cork re-glued at a musical instrument store after purchase.) It responds easily with little breath and gives the impression of producing a sound that is both soft and has a core.
