  Roadie positions itself as the next generation of guitar
tuners. Think of it like a modern String Master, a device that
fits snugly over your instrument's tuning pegs and does the hard
part for you. Paired with a companion smartphone app, Roadie
listens your guitar's strings and turns its gears until the
instrument is on key. We dropped by the team's table at Haxlr8r,
and the process was dead easy, quickly tuning a demo guitar
without breaking a string. In fact, it's designed not to -- by
comparing a string's elasticity with its frequency, the device
can actually warn you when your guitar's wires are about to
break. Not a bad trick, particularly for guitarists (like this
editor) that aren't completely sure when their instrument was
last restrung. The device's Kickstarter page has already more
than half of its $60,000 goal, and has a little over a month
left to get the rest. Looking for a way to chip in (and to avoid
guitar maintenance)? Check out the source link below; Roadie
tuners start at $79.  Roadie ha
