Trombone/Euphonium Mouthpiece Schilke Symphony Series D5.2 Large Shank Silver Plate Cup Diameter: Schilke 52, Bach 4G equivalent Slight scratches on the shank. Otherwise, no noticeable scratches are visible. [Product Description] *Quoted from Gakki-do HP ■ Schilke Trombone Mouthpiece Symphony Series From Schilke, which has completed its own mouthpiece lineup through dialogue and research with players over the past 50 years, comes the "Symphony Series" model for classical orchestra players. This lineup was developed by Carl Hammond, Schilke's custom mouthpiece designer, for classical orchestra trombone players. Based on the conventional standard Schilke lineup, the rim contour, cup shape, throat, and backbore have been modified. This provides a good balance between breath resistance and ease of passage. The clarity of the attack is also a major attraction for current players. #Schilke #schilke #Symphony #symphony #d52 #Trombone #Euphonium #Mouthpiece
