Hello, I've been playing the alto saxophone for roughly 4 years now, and recently I've run into a problem with my reeds. A lot of them sound spitty and somewhat airy when I play them, and many are hard to play even though I'm only using a size 3 reed. Any advice would be helpful. I have a reed geek reed filer, but I don't know exactly how to use it to effectively improve my reeds (advice there would also be helpful). For reference, I use Vandoren blue box size 3's, and also Vandoren java green size 3.5. I play on a Vandoren optimum al5 mouthpiece typically, but I use a Vandoren Java a55 mouthpiece when I play jazz.
