DIY: Turn your Guitar Hero controller into a Ukulele
Seems like a fairly rudimentary project, all you need is a Torx screwdriver, a small Phillips head screwdriver, a hacksaw, some glue, and some mending plates. You then take apart the donor guitar and perform the necessary surgery to make the neck smaller based on your particular needs. Of course it’s a bit more complicated then that, but feel free to read over the full instructions posted by the author.
