The Bach 3B is designed for players who want a fuller, broader sound with the familiar feel of the Bach 3 rim size. With a medium-deep cup and 16.30 mm diameter, it offers more depth and body than the standard 3C while still maintaining the clarity and response Bach mouthpieces are known for. The medium-wide rim provides stability and comfort, while the #7 backbore helps produce a warm, full tone with excellent projection. A strong choice for orchestral, symphonic, and classical artists who want a larger tonal palette without moving to an oversized rim diameter. Finished in silver plating for durability and a classic Bach look.
