• Genuine Vincent Bach mouthpieces are the best available in the world. Bach mouthpieces are designed to meet every conceivable playing need and have for nearly three quarters of a century.
• A Bach mouthpiece will make a poor instrument play well, a good instrument play better. Volume and excellent intonation, ease of response in the high and low register, rich, uniform timbre throughout the range, and resistance calculated to increase the player's endurance - these characteristics explain why the best professional artists choose Bach.
  
  Because Bach mouthpieces are the accepted standard of quality, their numbers are familiar everywhere as designations for certain models and types. Although Bach mouthpieces have often been copied, they have never been equaled for precision, tuning, and playing characteristics.
