Tight grain, old growth longleaf pine makes great calls, I made four trumpets out of some pine with very tight rings from a board cut over 100 years ago that sound like they were made from some kind of hardwood. All pine is not created equal, but old, slow growing pine makes good calls. I will try to get my daughter to post pictures of the trumpets later. I love the fact they are made from wood that is native to my area. The wood in these calls is very pretty and the CA finish really sets them off.
