You know those guitars with built-in motorised tuners? Now you can get a hand-held motorised tuner that'll do the job - and it keeps an eye on your string condition too. Neat.
Born from a KickStarter project, this little roadie doesn't drink all your beer, but gets on with tuning your guitar really quickly to a host of different tunings, all selectable via an App.
