For Crampon/YAMAHA Made of Grenadilla, equivalent to 42.0mm Can also accommodate B♭ clarinet reeds Used only for about 30 minutes of testing, it's practically new. This is a newly designed barrel to compensate for the weaknesses of the E♭ clarinet's sound, which tends to be high-pitched and weak, by increasing the mass. It extends the tube to cover the outside of the main body and secures the barrel mass without excessively increasing the tube thickness. My impression after playing it was that the overall sound became fuller, and the articulation and control in the high range were significantly easier. The intonation also seemed to be even, making it a controllable barrel. However, perhaps due to the increased mass, the blowing resistance felt a bit heavy to me, and I found it difficult to manage in terms of stamina, so I reluctantly decided to sell it. It's difficult to tell from the photos, but the wood grain is very beautiful, and the shape that covers the main body is adorable. It seems to be a rare barrel that is not yet widely available, so if you're interested in trying it, please consider it. Since the product originally doesn't come with accessories like a box, I will wrap it in bubble wrap for shipping. As a bonus, I will include the unused, brand-new cleaning cloth in the last photo, which I had on hand.
