Maybe I can help...Most crow calls can "stick". On most calls, the gap between the 2 mouthpieces is narrow. The reed is very close to either side of the mouthpieces. Sometimes if you get to much saliva in there it can make that reed actually lean over and stick itself to one side or the other. You can sometimes hold the call sideways and blow thru that gap sharply and break the reed loose...or, it doesn't stick to the side, there's just simply to much spit or debris in there to let the reed work right
Something else that can happen is that the reed, which is plastic, can warp a bit and lean over to one side so when you blow air thru the call, it will cause the reed to instantly push over to one side of the gap and lock up. Also, sometimes the reed can simply move or work itself out of position just enough so that it isn't covering the air channel just right, and will lock up or buzz or otherwise not blow clean..
There are crow calls that have a real wide gap that aren't prone to some of those problems. They have a different sound though, which can be good, and may take a bit more air to blow. Faulks for example, or a Mallardtone.
Everyone should learn to tune their call. Especially crow calls. Crow calls that use the tapered mouthpieces like a Gibson, are designed to be popped out easily and be cleaned and tuned...you clean em, and you can straighten reeds etc.
Calls that have a non-tapered mouthpiece, like a Mallardtone or Faulks, are a bit harder, as you may have to use a small dowel up thru the barrel to knock out the mouthpieces. They are sometimes stuck pretty good.
Anyways, I probably just muddied up the water here, but I will say that almost any reed type call can stick regardless of who made it. That's just the nature of the beast. That's why you need to take things apart and learn how to tune. Everything fails. Some are just more prone to wear and environment.
If I can help further just holler.
