Soprano Saxophone Mouthpiece Bobby Dukoff D5 (Metal Mouthpiece Vintage) Please refrain from purchasing if you are sensitive to the condition, as this is a used item. The material and sound are very similar to those from Miami, Florida, and it has a sound that current Dukoffs do not. Vintage Dukoffs are rare. Although it's a size 5 opening, it feels wide, and I felt it was easier to blow into. There are no noticeable scratches on the mouthpiece, table, or side rails. "Super Power Chamber" is engraved above the Dukoff lettering. Returns are not accepted as this is a used vintage item. I plan to list vintage items and famous instruments for sale to organize my collection, so thank you for your interest.
