Offering the same fan-favorite polyphonic, chromatic, strobe, and alternate tunings modes as its predecessor with the addition of a might Bonafide Buffer to preserve your tone, the TC Electronic Polytune 3 Polyphonic Tuner Pedal is an essential presence on any pedalboard. The 109-LED display gets you clear readings whether you're on a dark stage or sitting in your bedroom, and the diehard design ensures years of use. A must-have effect.
