The Vacchiano #4 Piccolo Mouthpiece
Inner diameter: .639" or 16.25mm
Bore Size = #25 ( .149" or 3.78mm)
The Vacchiano Piccolo models are designed with the symphonic player in mind. The emphasis is decidedly on sound. The cups are not extremely shallow, but just shallow enough to offer players who normally play on large orchestral equipment a spectrum switch in playability and color to enhance the upper register.
These models are available in either a trumpet or piccolo cornet shank.
