Jazz reeds don’t work for me. I have been playing Java, Rigotti and others for a while but in the end I’m loving a good old Blue Box Vandoren, once it’s adjusted (I compress the fibers on top with a reedgeek or fingernail) and a little broken in. I feel like my intonation is better, my sound is fuller, it just takes a little more effort to blow through but it’s worth it, actually I’m finding it’s essential to my sound. I tried a V12 too but prefer the Blue Box. I might try the V21’s but for now these are working well. In the past they seemed stuffy but practicing a lot has changed my embouchure I guess. These are suitable for playing jazz or any type of music. Anyone else into Blue Box Vandoren reeds?
