These mouthpieces, based on the original Vincent Bach design, offer excellent volume and intonation, ease of response in the high and low register, rich uniform timbre throughout the range, and resistance calculated to increase player endurance. The Bach mouthpiece numbering system is arranged in an orderly progression from the largest to smallest diameters numbered from low to high. Reviews There are no reviews yet.
