The TC Electronic PolyTune is a compact pedal tuner that stands out with its polyphonic mode, letting you strum all strings at once to see which are out of tune. Switch to chromatic or strobe modes for single-note precision, and it handles drop tunings or capo positions easily via a button cycle.
It comes with a built-in Bonafide Buffer to keep your signal clean over long cable runs, and you can toggle between buffer and true bypass. The LED display is bright and responsive, making it reliable on dark stages.
