Several important factors must be considered when answering the question of how to set up a 12-string guitar. This is essential for optimal performance and to avoid potential damage.
Let’s delve into the key aspects of setting up a 12-string guitar: strings, alignment, action, tuning, and maintenance.

Have you checked out some of the most outstanding 12-string guitars from Takamine?
Strings
Strings play a crucial role in setting up a 12-string guitar. Takamine 12-strings come from the factory equipped with D’Addario light gauge phosphor bronze sets (.010-.047). Sticking to the recommended string gauge ensures the proper tension on the neck.
Attempting to install two sets of phosphor bronze 6-string sets (.012-.053) can lead to excessive tension, which can cause potential problems and damage to the guitar. Instead, it is advisable to use two extra-light six-string sets (.010-.047), which will result in a tension of 266.5 pounds, which is within a safe range.
If you opt for strings from other manufacturers, it is essential to check the combined tension of the set using two sets.
For example, GHS Ultra Light Phosphor Bronze (.010-.046) exerts 232.6 pounds of tension, GHS Extra Light Thin-Core (.011-.046) exerts 243.6 pounds, and Elixir Extra Light Phosphor Bronze Nanoweb (.010-.047) exerts 270 pounds.
Always ensure that the total tension of the strings stays within a safe margin and does not exceed the recommended limits set by the guitar manufacturer.
Alignment and Action
Alignment and action are crucial factors in achieving optimal playability. Proper alignment ensures that the strings are evenly spaced across the fingerboard and that the neck is not twisted. The action, or string height, should be set according to your playing style and preference.
It is recommended to consult with a professional guitar technician to ensure precise alignment and action adjustments.

Tuning
Tuning is another vital aspect of setting up a 12-string guitar. Use a reliable tuner and follow the standard tuning for a 12-string guitar: E, A, D, G, B, E, from low to high. Ensure each string is tuned accurately to maintain proper intonation and a balanced sound.
As there are high and low octave sets for all strings. Be careful while tuning.

Maintenance
Maintenance is key to keeping your 12-string guitar in optimal condition. Regularly clean the strings, fretboard, and body using appropriate guitar cleaning products. Keep the guitar adequately humidified to prevent damage caused by changes in humidity. Additionally, inspect the instrument for any signs of wear or damage and address them promptly to avoid further complications.
How to set up a 12-string guitar: DIY or Expert Support?
When it came to getting my 12-string guitar just right, I had to decide: Should I do it myself or get some expert help? As someone who loves playing, I’ve tried both options. Doing it on my own seemed cool, but it’s quite tricky. Tweaking things like the truss rod, bridge, and nut and making sure all the strings sound good can be tough.
It’s easy to mess up. Conversely, a guitar expert, also called a luthier, knows their stuff. They can set up the guitar perfectly, adjusting everything to feel and sound incredible. So, I’ve found that expert help is the way to go for the best results.
