It is one of those that you need to find the right reed for (2.5 VanDoren Green Java in my case) and give a second try if it does not work for you the first time

The larger tip opening allows for a softer reed if you want to play low notes as well.

Honestly, I really don't like Rico reeds, so when I snagged this mouthpiece for the price I did (it was quite a bit lower than it is here

Plays easy with a soft reed

I'm using the M7, with a medium soft reed.

Sounds above average when paired with a good reed, but doesn't sound great
