Features & Capabilities

Simple 12-string guitar tuner to tune up your 12-string guitar. This is for the standard eEaAdDgGBBEE 12 String Guitar tuning.

Tuning your guitar can be a difficult task for you if you are just beginning guitar. The good news is, the more you do it, the easier it becomes. A nicely tuned guitar can make your music sound a lot better and help you greatly while you're are just getting the hang of finger placement for notes.

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 it's 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 it's other string in the pair. This is eEaAdDgGBBEE tuning. The lowercase letters means that it is one octave higher then it's counterpart.

Touch the note for the string you want to tune and then turn the tuning pegs on your guitar and match it up with the note that is being played.

Tip: Make several passes tuning each of the strings. For example you might have noticed that if you have tuned all the strings once, and then back to the first one you tuned, it might be off a little bit. This is because you are increasing or decreasing the tension on each of the strings as you tune it and the instrument's body might bend ever so slightly due to this difference in tension. This causes the other strings to slightly change in pitch. So make sure you keep on checking and tuning the strings until all are in tune, so make several passes.

Also you can use this simple tuner for your standard 6-String Guitar, it is the same tuning, only the strings on the 6-String Guitar are EADGBBEE, which is right part of this 12-String Guitar Tuner. So use just right part of this tuner to tune up your 6-String Guitar.

User Reviews

Most reviews condemn this app as not a real tuner: it only plays predefined tones and offers no pitch detection, mic input, or visual tuning feedback, forcing users to match tones by ear. Many callers label it a waste of money and a scam. A minority find it fast, easy, and helpful for quick 12-string tuning and ear training. A recurring issue is octave misalignment on the high string. Overall, the app is controversial: praised for simplicity by some, rejected by most.

Cons
