 * _gfxg 
 
 Allows you to transform it into a a USB game controller for use with [Clone Hero](https://clonehero.net)/[DTXAL](http://senamih.com/dtxal)/Guitar Hero/GuitarFreaks/Gitadora. For instructions on how to convert an existing guitar into one, [check out 573controller's wiki](https://github.com/limyz/573controller/wiki/DIY-Guitar).
