Age-old question, but I'd love to hear your favorite gear/techniques for capturing the singing, acoustic guitar player.

There's a pretty good description of my ACO/VOC mic setup for Chris Stapleton here..https://www.gearslutz.com/board/12945863-post2.html
He's a perfect client as he sings and plays at exactly the right level to make this work.. Sometimes it's a bit tougher, but this or something close would be where I would start.
