NONDK Silver-Plated (6 1/2AL) Mouthpiece Thin Tenor Trombone Mouthpiece Pull Pipe Instrument Replacement Accessories

Rim shape: Medium width, round. Material: The trombone's gold-plated mouthpiece is made of brass and has a medium cup size of 6-1/2AL, allowing the player to produce a full, rich tone with relative ease. Great for all-around use. Tone: Similar rim and cup to the 6-1/2A, but with slightly larger throat and backholes, providing quicker response and ease of play. MANUFACTURING PROCESS: The inner walls of these mouthpieces are smooth and neat because they have undergone multiple grinding processes.
