Griego CS5 mouthpiece for large-bore trombones. I have several, so I'm offering one to anyone interested. The CS series is designed with a strong emphasis on balance, offering: "Fast response without thin sound" "Not too light, not too heavy, with a core sound" It's a model within Griego that's positioned for those "in the know." Specifications: ・Rim Inner Diameter: Approximately 25.50mm ・Throat Diameter: Approximately 7.21mm ・For large-bore trombones ・Classical-oriented (suitable for orchestra/wind band) This CS5, while the numbers might suggest a slightly compact feel, actually allows the sound to naturally coalesce and is less prone to breaking up even at forte. It avoids the "sound scattering sideways" characteristic of lightweight models, and is a mouthpiece that projects forward with a maintained core sound. ※The CS series isn't flashy, but it's a series that tends to be highly regarded for: **"Sound that doesn't collapse" and "beautiful recorded sound."** This model sells for around 30,000 yen new overseas, and it's a model number that's somewhat difficult to obtain individually in Japan. Condition is almost like new. There are no noticeable scratches or dents on the rim or shank. "A type that doesn't force the sound with the mouthpiece, but rather translates the player's breath and embouchure into sound directly." In Japan, it's only available as an accessory for Getzen trombones, but it also seems to work very well with Yamaha trombones. I think this will be a great fit for those looking for such a mouthpiece.
