TC Electronic PolyTune 2


Along with Boss’s TU-2/TU-3, the PolyTune 2 is one of the most popular pedal tuners ever built — and for good reason. With its sleek Scandinavian looks, six-string polyphonic tuning capability and ±0.1 cent accuracy (in Strobe mode), the PolyTune 2 delivers outstanding tuner technology in a nice-looking package.
