It will always be an easier experience on your students as players and you and their loved ones as listeners if they are performing on handmade and adjusted bassoon reeds, as opposed to machine manufactured.
I can personally recommend the following reed makers who supply high quality, handmade reeds for a variety of performance levels.
I also make and sell a very limited number of reeds for my local and virtual private students. Feel free to explore my Storefront to check my availability and turnaround time for small orders.
