He makes an awesome call!
I have his slate, copper, brass and titanium.
They all have a different quality to their sound, and can't say I have a favorite as of yet.
The brass seems like it will be getting the most play for now, it has such a raspy back end...it makes me feel all warm and fuzzy when I play it.
but his titanium is just fantastic as well....it can purr and cluck as soft as you want, and can really scream when you get on it...
He's a great guy to deal with, and truly makes a quality product
