Hi J.P.......I have a mate who has got a EVH Wolfgang and they have a Maple Neck & FB where both are pretty well naked. He sands the back with 1200 to 1500 wet & dry paper (dry) and puts lemon oil on the Fret Board even though the bottle says only for Rosewood. Raw maple will look reliced pretty quickly if left untreated and allowed to soak up lots of sweat, beer, smoke, etc that you may encounter playing live.
On my J Bass I actually coated the FB with about 5 - 6 coats of Tru Oil and once cured sanded back with 0000 steel wool to take an edge off the shine to give a bit more of a satin look. Did the same trick on the back of the neck on another Bass as the 0000 steel wool doesn't clog up as quick as the W & D paper and you end up with a super smooth and fast neck.
