Hi, I'm new to the group and turkey pot call making in general. The info here is awesome and everyone seems very helpful. My question is this, if I have two indentical 3.25 pot calls slate over glass and the only difference is the soundboard diameter, one being 2.75 and one being 2.5, what difference in tone should I expect to hear? Same rasp just a more hollow sound? Less rasp? Deeper tone? Thanks for any input.
