Sorry, I guess I lead you all wrong. The neck is graphite, but it has an ebony finger board. So the Lemon oil would do just fine.
Off topic a bit. David, funny, I played with a guy named David Houk in Albuquerque, many moons ago. I suspect you are not the same David Houk.
I have not posted any pics of this bass, but will, It's a looker, and well a playa....
As I remember, Mica said there were less than 50 graphite neck basses made. This is a 1979, original owner, with Coco Bolo top and back. I know I know, it doesn't exist if there are no pictures.....
