Work from the sixth string to the first
Standard tuning from the thickest string is E2, A2, D3, G3, B3, E4. Select the standard-guitar preset, pluck one open string near its normal playing position and let the first transient settle. Turn the correct machine head in small movements until the note name matches and the cents reading stays close to zero.
- 6th to 1st: E A D G B E
- Let the initial attack settle
- Turn the tuner in small movements
Finish by checking the strings again
Changing one string can slightly redistribute neck and bridge tension, especially after restringing. Recheck all six strings, listen to a familiar chord and confirm that no string was tuned to the correct letter in the wrong octave. GuitarTool shows cents, frequency, input strength and stability without saving or uploading microphone audio.
