I’m not sure if this is a good or a bad way, but I finished a raw maple fretboard on a squier I had with some cabothane (cabots poly finish) that I thinned down to turn it down to a wipe on poly and put a drop or two of feast Watson prooftint dye/stain. They have heaps of ambers and browns to choose from, so you can get a slightly yellow finish all the way to the Mexican fender classic series level of orange
