Just got my new Brad Roberts Bocote aluminum over slate. I like it, it definitely has a different sound from any other call in my arsenal. It's my first aluminum call, so maybe that's why. A lot heavier than any other call I own as well. I'll try to get a sound file up sometime as well. Beautiful call, and communication with him was great, probably won't be my last one from him.
Congrats!! Fine callmaker!!
