Dear bassoon players. I play a baroque bassoon, model haka and I don`t find the perfect reed for my basson. If anybody play this model and wants to explain me the measurements and the shape of his reed, for me would be very important. Thankyou.

This is a most unusual instrument and I think you will have to go to a more professional source to find information on reeds, such as someone who sells these bassoons. Such a person can be found at the following email address:

They might be able to give you more information.
