Griego Deco 5M Trombone Mouthpiece, Large Shank This is the Deco model, a large shank mouthpiece developed by Mr. Griego, an engineer in the trombone development department of the American company Getzen. *The Deco model is a heavy-type mouthpiece. Size: 5M Cup Inner Diameter: 25.5mm Throat Diameter: 7.09mm I am selling this because I recently purchased a new mouthpiece and no longer use this one. I purchased it new from a musical instrument store in Japan. I used it about twice a month for about 11 months. There are some scratches on the shank from normal use, but otherwise, there are no scratches or dents, and I think the condition is quite clean. However, please understand that this is a used item before purchasing. I will pack it with bubble wrap and send it via Takkyubin Compact. The cup is the general 5G size, and the depth is slightly shallower than 5G. Needless to say, it has a high affinity with Getzen and Edwards, and you can get a sense of unity in the sound. Also, perhaps because it is a heavy type, I had the impression that it was easier to control when blowing air. Suggested Retail Price: ¥36,850 (tax included)
