The Vacchiano Signature Model #1
Inner Diameter = .688" or 17.5mm
This model is a copy of the primary mouthpiece that William Vacchiano used during his 38 year career with the New York Philharmonic Orchestra. The original featured the B cup with a #25 bore (3.78mm). The back bore on the original is the special Bukur style ("B") back bore that is the standard back bore for the entire Vacchiano line.
We have augmented this model to finally include all the different cup depths and variant options that we offer in our other models. This should make customizing this piece to fit your needs all the more easier!
