Any gigging musician knows getting on stage without something as essential as a tuner pedal is absurd. Tuning pedals incorporate a variety of methods like chromatic or polyphonic tuning and LED or strobe display to pin down tunings from standard to Open D to Drop C. Whether you prefer a classic experience like the Boss TU-3 Chromatic Tuner or the newcomer TC Electronic Polytune, one thing is clear: you're not going anywhere if you're not in tune.
