[Rare] Marmaduke Alto JAZZ Model (Prototype) Marmaduke Alto Saxophone Jazz Model (Prototype) Description: This is a prototype of the Alto JAZZ Model. It's not listed in the catalog or on the website and is not usually sold. However, I liked the sound and purchased it at a Marmaduke store where they were selling prototypes. It's easy to blow into and control, and it produces a natural sound, making it recommended for beginners. I mainly play tenor, but I used this alto for about two years. I am selling it to organize my saxophone accessories because I have been using other mouthpieces as my main ones. Condition: There are some minor scratches because I used it without a patch, but there are no marks that would indicate wear. There is no history of dropping it, so the table and facing are both in beautiful condition.
