When it comes to jazz tone, there's 3 things to keep in mind: the horn, the mouthpiece, and the reeds. These are those reeds to give you the best jazz tone possible. I use these for most of my playing, whether that's at home, in the studio, or in a performance. They have great response with a slightly heavier feel on the tip of the tongue. I use 2 1/2 for a relaxed, calm tone while still being able to rip high notes, low notes, and loud notes. Essential for every jazz artist's accessories, I would recommend these reeds all day, every day!
