I need help with making my call sound less raspy and a lower pitch.

[Mini me]

I am very new to using diaphragm calls and can't quite get the tone or timing for my yelps and I need some tips.

Could be the diaphragm that u use that just can't sound how you want. Maybe try another one, as simple as this...

Is it a store bought or one you made? Just to make sure...
And second question is, is it tripple reed or double?
