We haven't seen much reason to trade up from our ancient Boss tuner in all the years we've been playing guitar, but the new TC Electronic PolyTune might finally persuade us. Billed as the "world's first polyphonic tuner," the PolyTune supposedly lets you tune all your strings at once -- you simply strum away and the display tells you which strings need a tweak. 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. No word on price or availability, but we should find out more at NAMM this week. Check out a video of the prototype in action after the break.
