I just got a mahogany neck. It feels beautifully smooth. The only place I can detect any pores is on the angled areas transitioning to the neck and heel. Do I need to grain fill for any protective reason or is it just for the feel. It will of course be finished, in either Tru-Oil like the body or satin nitro. I like the satin feel of a high end Fender.What little pores there are are barely noticeable and I imagine will be gone from any finish I put on.
