I have a Spector American bolt on NS-JH-5 with an ash body. Many NS-JH-5's I see on the net are maple bodies or ash with a top option. The number on the back of the headstock is #058 that's hand written and a build date of 11/20/00. My bass doesn't have a top option, it's a maple neck, Pau Ferro fingerboard with small marker dots. Is this a rare bass? I don't see any others like it.
