Pickett Doc C Trumpet Mouthpiece This is the model of the highly-regarded Doc Severinsen. In my personal opinion, the design is very beautiful and provides a sense of satisfaction when used. It's a two-piece design. The inner rim diameter feels smaller than a Bach 3C. The cup shape is different from Bach, so it's difficult to compare, but even I, who don't particularly like the 3C, was able to use it. - Finish: Silver-plated - Type: Trumpet mouthpiece - Design: Two-piece - Usage: For practice Thank you for looking.
