Similar in size to No.9 and in tone to the more brilliant No.7D. Players with narrow, sensitive lips get satisfactory results with this model. Recommended for the extreme high register. Vincent Bach was a rare combination of artist and engineer. A mechanical genius and acclaimed trumpet soloist, his instruments and mouthpieces are used today in every major studio and orchestra in the world. Bach personally designed the tools and composed the plans that continue to set the high standards for making all Bach products today.
