I made exactly that finish on a guitar a few years ago. Sand back to open pores, shoot a sealer coat or two of shellack of stor the neck step to make a mess, grain fill with a black (blackened) pore filler, sand off any excess until you have exactly the grains highlighted and nothing else of the pore filler remaining on the body, shoot another sealer coat or two of shellack, shoot a semitransparent white finish until you have exactly the coverage you desire, shoot a couple of protective layers of clear, sand flat (without sanding through!!!) and shoot one or two layers of semi gloss as final layers. I cannot stress the need for sealing coats of shellack (or other good sealer) as I had the pigments of the black pore filler bleeding through the white on the first attempts (probably technically wrong description, but thats what it looked like) making me have to go back and sand everything off. And always test om scrap
