Schilke Cornet 6A4a

I bought this one to use with my piccolo because it was described as "bright". It fits me perfectly, it has a very nice rim that feels comfortable and doesn't cut into your lip even if pressed hard (but you will not need to press, it respond very easy).
It makes playing high notes easy, without making the sound thin and lifeless (like most small mouthpieces).
The sound is very bright and open.
