Extremely rare IslRich ECO 4G AAL Euphonium/Trombone mouthpiece with a large shank and a plastic rim. I really don't want to sell this mouthpiece... This is a euphonium/trombone mouthpiece (large shank) made by Airlich (now EPM), a Japanese workshop. The detailed specifications are unknown, but personally, I feel it's similar to a Bach 4G. I find it easy to play, produces a soft sound, and is less tiring. It's also perfect for those with metal allergies or for practice and performance in winter – it's not cold! Original box - None I've used it several times, but there are no noticeable scratches or dents. Please check the photos. This is a used item, so please understand. Please refrain from purchasing if you are overly sensitive. No returns or exchanges, please.
