Natural Tru Oil is my go to on a raw Maple neck & fretboard as it has a light amber tint that ages quite rapidly.
If you go for an aged amber tint from the start and then use Tru Oil you may end up quite surprised at how dark it becomes after even 12 months.
I have used the stuff on all 7 builds and the natural finishes are much richer and darker now which was a surprise given that they all live in hard cases and kept out of direct sunlight.
