GREG BLACK Trumpet Mouthpiece 1-1/2C This is a one-piece model. The response is very good, and I think it's a mouthpiece that suits any genre, from classical to pop. The slightly smaller 3C suits me better, so I'm going to let this one go. There are a few scratches on the shank, but I think it's in beautiful condition. Silver-plated finish Size: 1-1/2C (16.9mm) Cup: Medium-Deep ~A highly refined mouthpiece from a world-class craftsman~ Greg Black, who was directly instructed in the production of custom mouthpieces by Bob Giardinelli (founder of Giardinelli), has a long history of setting up a workshop near New York, and has been receiving requests from players mainly in New York. In recent years, the brand has an image as a manufacturer of trombone mouthpieces, but he was also a trumpet player who performed before becoming independent and has a bachelor's degree in music. In fact, many trumpet players love to use it regardless of genre, and on the other hand, because he makes each one by hand using traditional methods, it is known as one of the most difficult mouthpieces to obtain, even though they are still being made today.
