I wanted to improve on the standard Mini tuners, so the first thing I did was put on a set of tuners from a full sized Taylor that I had put Gotoh's on. I thought the new tuners were better (less slop, stayed in tune longer), but looked a little large. I then tried changing the tuner buttons. I put the original tuner buttons from the GSmini tuners on the full-sized tuners. They fit, but were a little tight when I later removed them. That improved the looks. I was satisfied with that until I got a good deal (used) on the mini tuners from a Taylor 12-string. They are the same size as the original GSmini tuners, but have the quality of the full-size tuners. I am very satisfied with those. By the way, all of the tuners fit the holes in the headstock with no adjustments.
