For those who prefer a slate call in 3.0 inch here's a three track player in Black Limba. This one turned out to be a bit particular to the striker and can be more finicky that the say copper calls. I ended up pairing it with a hickory striker that gives a high pitched raspy yelp while the Ipe striker is toned down a bit yet still with rasp. 155.00 shipped with  strikers and logo embossed leather pouch.
