Never stained a bow of maple, but I stained a lot of wood in my painting business, and maple is a hard wood to get to take any kind of stain. That is why a lot of times you see maple is left clear. you could use a much darker stain than you think you want. it will come out lighter on maple. experiment on scrap.
a light sanding with very fine paper or 0000 steel wool may help too.
depending how dark you want it to go, you may have to use multiple coats, letting it dry all the way in between. If you try to do it too soon you will pull out the stain from the previous coat.
Staining in my eyes is more art than science. Good luck and have fun.
