After talking to a lot of people here locally about what they want in a duck call, I found that the large majority want a double reed. Could be becuase we're all a bunch of amateurs, but even some friends that are not prefer the double.
When I first started I started on single reeds. They were just easier to tune in my opinion. however, I'm to the point now where I only make double reeds. this is very different and tricky as my main complaint is "too hard to blow" so I've had to work a lot to fix that. I actually just sent a call to another builder I met online and he said the sound is spot on, and he's been making them for years now. I plan to send it to some more people for them to run.
I start by cutting out the toneboard of course. I make sure everything is square and the sides are equal.
Next I put 2 full reeds on the board. Then I start to tune the reeds. I start by cutting the top one back just a little bit. After that, I cut them both at the same time, but keep that small difference between top and bottom. After it's really close I may sand the board just a bit but very little. I don't tune 1 reed then put another on top of it.
I do the same thing with my single reeds.
