I used acetone on a few of my Gibsons before refinishing them or when I wanted an unfinished neck. It works great. I can't stand it when guys sand down their Gibsons! In a couple hours I'll add a pic of a Flying V with a neck I just stripped. Don't leave it unfinished though, because then dirt and oils from your skin will get into the wood grain and make it look dirty and gross. Use gunstock oil on it after all the finish is removed. I use Birchwood Casey Tru-Oil.
