World's first polyphonic tuner for musicians

TC Electronic PolyTune lets you tune all your strings at once. All you do is strum and the display tells you which strings need to be tweaked. There's also a standard needle mode, two chromatic modes, a real-time stream mode that shows you pitch changes as they happen, and built-in memory so you can lock in your favorite settings. Currently, there is word on price or availability. Check out a video preview after the break.
