This model is reminiscent of the Brilhart mouthpiece favored by Charlie Parker, a.k.a. "Goz." It is finished with exquisite detail. As the name "Bebop" suggests, the high overtones are moderately suppressed, resulting in a dark and resonant sound. It's not as linear as a Meyer, nor is it too fat like a soloist. Gottsu mouthpieces have always given the impression of being bright and responsive even with a light blow, but this one truly "responds to how you blow." Soft notes sound soft, and loud notes sound loud. It may seem obvious, but it's very important. The player controls the tone and volume, without any unnecessary embellishment. I feel like this mouthpiece gives you the sensation of singing. Used for about a month, there are some areas with slight clouding due to the material's characteristics. Also, the paint on the "Sepia Tone" engraving is slightly chipped. There are also slight tooth marks. There are no problems with use, but please be aware of this. Everything in the images is included. Please understand that this is a used item before purchasing. Returns are not accepted after purchase. If you have any concerns, please feel free to ask questions in advance. Thank you.
