Several people have asked me for a soundfile so here it is. I hate doing soundfiles because I don't feel I am a very good player and take away from the makers works of art.
I started with the Persimmon Wood Striker that came with the call, then went to the Waterproof Striker of John's and then used one of Jeff's (JHL's) Frogwood Strikers.
