Maybe I'm just crazy, or have missed the obvious here. Has anyone else noticed that wood barreled trumpet calls seem to be harder to play in early mornings when the temperature is a little colder? Those same trumpets run easier and better in the afternoons when the temps rise. Could be something I'm doing wrong. I've been very proficient with mouth calls, box calls, and pot calls for years, but only picked up the trumpets about three years ago. Anyone else notice this or am I missing something?
