How to Tune a Bass Guitar Online (EADG)
Standard 4-string bass tuning is E1-A1-D2-G2. Pluck one string firmly and let it ring, then bring the needle into the green zone. Low notes decay slowly and carry strong harmonics, so give the tuner a second to settle after each pluck before you turn the peg.
If you tune through an amp, keep the volume modest and the tone clean — distortion confuses pitch detection. Always tune up to the target note, and re-check the low E after tuning the others, since neck tension shifts as you go. Your audio never leaves your device.
