The howler is still available. I have been thinking of building a handmade board for it, as it really deserves it, it's a beautiful body. The KO is a great sounding board, but it's not pretty.
No other calls on the shelf right now, everything has sold. I have more camo PVC calls, but that's it. I've been building extra fancy lam calls, and they've been selling. Got another one on the way, but nothing sitting, that's for sure!
