I have an elk reed and it looks like they're pretty similar, so I'll give this a shot
If you don't know, you use the reed kind of like how you say the letter 'ch' like cheddar. Your tongue goes to the roof of your mouth, leaving a teeny gap so the air can pass through. That's where you know to put it, and how to make it do the sounds without the air just going around another way.
Do you know to move your mouth when making the calls to create different sounds? I also mix in some of my own noises, like a purr/growl thing when I'm using my reed to make a more gentle sound. The sounds are also a lot quieter in suit, which I was worried about, because the elk reed is LOUD!
It also takes a lot of practice to even figure out -where- to put the darn thing in your mouth
I eventually figured out pushing the reed so it stayed on the top of my mouth and kind of curling my tongue under the latex made the best sounds. And if you can't make a sound with it, try flipping it over. The instructions on my elk reed were incorrect, saying the curved end should go with the curve of your teeth, but I couldn't make a noise. I switched it so the latex was towards the front, and it worked (I could be switched around, but I knnow the opposite of what the directions said worked.)
If the instructions don't say so, putting the reed in the refrigerator -after- it has dried helps protect the paper/latex from loosing its flexibility. Rinsing with cool water after you use it is a good idea, and some people let their reed soak in mouthwash, but don't leave it in there for too long.
If you wanted to, I'll see if I can do a video about where I put mine and whatnot, but I'll be out of town for the weekend, so I might have to do it on Tuesday.
