The following maybe a bit scary for some, you may not get to the end of the post, others may scream at their computer / tablet screen, well here goes. Not to long ago I bought a Squire Stratocaster model Vintage Modified 70s, thought it a great Guitar for the money, but, here we go. The neck and fret board is a very nice high gloss Maple, found the fret board nice no problem, but the neck, my hand kept sticking to it like glue, it made the Guitar almost unplayable for me, then bright idea, got some wet and dry gray looking sandpaper, and gently sanded the back of the neck, if you held the guitar up to the light, you could see it had taken the gloss off, but not gone through to the bare wood. The overall result was, the best guitar neck I have ever had on any guitar, for playability, and from a visual point of view, very pleasing to the eye, and unless inspected very very carefully, you would not know any sanding had taken place. If I find the same problem on any other of my guitars be it electrical or acoustic Iwill do the same neck sanding.
Derick, I did that to a guitar once as well. Can't remember which one; though I "think" it was my Takamine. Only difference is I went a little more cautiously about it. I used a green scotch pad and it probably took be 4 times as long (at least) as the way you did it, but I knew I wouldn't be in danger of breaking through to the bare wood. I eventually sold it years later and even the guitar tech who inspected and appraised the guitar could not tell that what I had done was not the way it came. So ya, great solution as long as you get it right!

Haven't tried sanding the neck of any of my Acoustic Guitars, but if I get an Acoustic Guitar with a high gloss neck, I would not hesitate in sanding the neck, as you have stated not down to bare wood, just to remove the high gloss finish, just nice and gently, but looking with the light reflecting of the neck, you can see where the gloss has been removed. 😀
