Are guitar tuners accurate?

Most digital tuners are accurate within 1-2 cents. The human ear usually can't tell the difference between 5 cents. However, when you play chords, smaller inaccuracies may be heard. Usually, you'll hear a pulsating or throbbing sound.

Do you need a guitar tuner?

A good tuner is essential to any amateur or professional guitarist who wants to maintain a true and consistent sound for guitar chords and individual notes. A guitar that's even slightly out of tune can derail an otherwise excellent performance, so the best players insist upon accurate tuning via an electronic tuner.

How does a guitar tuner work?

When the musician plays a single note, the tuner senses the pitch. The tuner then displays the pitch in relation to the desired pitch, and indicates whether the input pitch is lower, higher, or equal to the desired pitch.
