@LeftyJ,
One other thing... if you look at the image top right on the 1981 catalog page that I refered to above - see [url="http://s93105080.onlinehome.us/Ibanez-Catalogs/catalog/1981/12.jpg"]http://s93105080.onlinehome.us/Ibanez-Catalogs/catalog/1981/12.jpg[/url] immediately above "24-fret models" - you'll note that the fretboard on that bass is also very dark. That said, the bodywork on that bass doesn't seem to fit other Roadster models on that page so this image might well be a red herring ??
