AR Resonance Euphonium Mouthpiece (for large shank) top and backbore. Model is the current signature model of Glenn Van Looy (GVL). Purchased new and used a few times, so it is almost new and in excellent condition. [Contents] AR Resonance Mouthpiece GVL model for Euphonium Top [Material] Nickel [Plating] Silver plate finish Backbore Bronze Silver plate M72E size ※Note: Box and leather case are not included. Will be packed in bubble wrap for shipping. ※Note: Although this item is almost new, it has been used to some extent, so it is a used item. Please understand this point, and especially those who are sensitive to this should refrain from purchasing. Please consider purchasing only if you understand the above points. ※Reference: This manufacturer's mouthpieces are separate top and backbore, allowing for various combinations. I mainly used this top in combination with a bronze backbore, and my personal impression is that while maintaining a core, thick tone, the response and the reach of the sound are particularly enhanced. Please refer to the information from the domestic distributor for the current price (new). https://trumpet-store.jimdofree.com/ #Euphonium #Mouthpiece #Trombone
