Somewhere out there is a Rick one-off walnut 4003 with a shiny clearcoat finish. It is fabulous looking. To the OP,just be aware the walnuts oil finish can make the maple fretboard look dingey fairly quick. I love the feel of it on my Cheyenne 1,but not crazy about the "dirty" look.I wasn't shooting that high.
I was just thinking of what could EASILY be done by Rickenbacker, if they had the desire to.
As it is, realistically, they'd just probably look at the photo and tell him to go ____ himself.
Edit-and i really don't like the look of thr pearl fwi on a maple fretboard.
