Hipshot makes a bevy of great tuners that will fit your GS Mini. Some also come with the cool option plates, that require no new drilling, and work with the new, no screw Taylor tuners. Most are 1:18 gearing...Great products, at a great price, if you know where to look (eBay)...I have changed out a number of my guitars to the Hipshot, including the Baby, and the GS-Mini...
