Monette AP4 Piccolo Trumpet Mouthpiece

This is a mouthpiece developed for A-flat piccolo trumpets.
It is designed to make it easy to find the sweet spot of the sound, based on Monette's Pitch Center Theory. The size is approximately between Bach 1-1/2 and 3.
The rim is flat and slightly thick. It is a very soft-feeling rim.
The cup is about a Bach E.
The throat is slightly larger than a #24 (3.86mm).
Although it has a large throat, the straight section is slightly longer, designed for stable high-note performance.
Pitch control is easy, aiding in stable playing.
It produces a brilliant, full, and rich sound characteristic of Monette.
Piccolo trumpets are often played in A-flat. How about this hard-to-find mouthpiece in Japan?
