How to Use an Automatic Guitar Tuner

Identify what the proper tuning of your guitar should be. Standard tuning (beginning with thickest string and going to the thinnest strings) is: e, a, d, g, b, e.

Locate your automatic guitar tuner and make sure you have a charged battery.

Identify whether you have an electric or needle style guitar tuner. Electric guitar tuners will have a series of lights, and the needle style tuner will have a little needle that jumps to set the proper tuning.

Choose the string you want to tune first and set the tuner so that it is ready to test that particular string.

Pluck the string. The electronic tuner will turn green if it is in proper tuning. The needle tuner will hover directly in the center when the string is in tune.

Turn the tuning pegs at the top of the guitar headstock to change the tuning. If the tuning is too high, lower the string by turning the peg to loosen the string tension. If the string is too low, tighten the string tension.

Repeat steps 4 to 6 of all the strings after the first string has been successfully tuned.


  • Only tighten the strings slowly and a quarter turn at a time to avoid accidentally snapping a string.
