Online 12 String Guitar Tuner

Use this free online 12 string guitar tuner to tune up your guitar. This is for the standard eEaAdDgGBBEE 12 String Guitar tuning. A 12 string guitar is split up into 6 pairs of 2 strings. The thicker string of the pair is tuned to the same note and octave as a regular 6 string guitar. The thinner string, on the pair of strings 3-6, is tuned one octave higher than its pair. On the first and second pairs, the notes are the same octave and each string in the pair should sound exactly the same to its other string in the pair. This is eEaAdDgGBBEE tuning. The lowercase letters means that it is one octave higher then its counterpart.

Alternate Tunings

If you need a different tuning then, check out our adjustable guitar tuner, and select the tuning you want and then tune the thicker strings it like you would a 6 string guitar and ignore the smaller string of the pair. Once you've done that, go back and tune the thinner strings 1 octave higher to whatever the notes is on the thicker string. Do this with all the strings except on the 1st and 2nd pair. Like we mentioned earlier, the first and second pair of strings are the same octave so just tune it to the exact note of its other string in the pair.
