the fretboard looks to be rosewood and not ebony. There's a possibility it was a custom order.
It also looks like there is a thick veneer type overlay on the peghead. Do you have a pic of it?
I also thought the fb looked like not ebony. But, it does have black streaks and most ebony is not solid black, so I'm not sure about that.
I didn't notice the peghead looking odd. I just went back to GC Used to look at their picture again and the bass is gone! Did somebody here snake it out from under me?!?!
