Why does your 12-string guitar go out of tune?

¿Por qué se desafina tu docerola? - Karma Guitars, Inc.

Tension: The Real Culprit

A docerola carries twice as many strings as a normal guitar, and that means a lot more tension pulling on the neck and soundboard, all the time. When that force isn't properly contained, the neck moves a little bit and the tuning goes off. That's why a cheap docerola, built as if it were a six-string with extra strings, constantly goes out of tune.

New Strings, Climate, and Nut

There are three more suspects. One: new strings stretch in the first few days; it's normal for it to go out of tune at first, it's not a defect. Two: the climate. Wood moves with humidity and heat — from the coast to the mountains, your guitar changes. Three: the nut. If the grooves are poorly cut, the string gets stuck there and 'jumps' out of tune every time you stretch it.

How to Keep It in Tune

Always tune by going up to the note, never down: this way the string sits well in the nut. When you put on new strings, stretch them by hand and retune several times until they settle. Store it in its case and, if you can, maintain humidity between 45 and 55%. And check that the nut is properly cut for your gauge; if the string buzzes when tuning, that's the problem.

How KARMA solves it. Every KARMA docerola comes with an adjustable dual-action truss rod, so the neck is easily corrected for climate changes. The nut is made of bone and is specifically cut for paired strings (10-47 gauge), not for a generic guitar. And it arrives with its paired strings installed and factory-intonated, ready to play on day one.

Frequently Asked Questions

How do you tune a docerola?

In standard tuning, but with paired strings: each note is doubled. On KARMA docerolas, the paired strings are tuned in unison, with a 10-47 gauge.

Is it normal for a new docerola to go out of tune in the first few days?

Yes. New strings stretch and need to settle. Tune it several times for the first couple of days, and then it will stabilize.

Do I tune it up or down to the note?

Always up. If you went too far, go below and come back up. This way the string doesn't get stuck in the nut.

¿Las docerolas laminadas valen v...? La verdad sobre las tapas laminadas y sólidas. - Karma Guitars, Inc.

Are laminated tops worth it? The truth about laminated and solid tops.

It's not as simple as "laminated = sh*t". Solid tops vibrate more freely, project more, and mature with age; laminated tops project a little less but withstand bumps and climate changes better, ideal for rough use. For recording or for the guitar to 'breathe', look for solid; for your first 12-string or for everyday use, a good laminated one will do the trick, BE CAREFUL not to be fooled, there are laminated guitars and then there are laminated guitars.

¿Se le arquea la tapa o se levanta el puente a tu docerola? - Karma Guitars, Inc.

Is the top of your docearola arching or is the bridge lifting?

The top arches up ("gets a little belly") and the bridge lifts because the 12 strings pull with enormous force, and over the years, a poorly reinforced top will yield. This is prevented with well-designed bracing, a reinforced bridge, and a factory-installed Bridge Doctor, in addition to maintaining stable humidity.

Why does your 12-string guitar go out of tune?

A twelve-string guitar goes out of tune mainly due to the enormous tension of its 12 strings, new strings that haven't settled yet, changes in climate, and a poorly cut nut. This can be controlled by always tuning 'upwards', stretching new strings, maintaining stable humidity (45–55%), and using a guitar with an adjustable truss rod and a nut cut for paired strings.

How to string your 12-string guitar without it becoming a nightmare

To string your twelve-string guitar without trouble: change a few strings at a time (never all 12 at once) so as not to suddenly release all the tension from the top; respect the position of each pair as they were originally; wind evenly and downwards on each tuning peg; stretch each new string by hand and retune several times until it settles. Always use the correct gauge (pair strings 10-47) to avoid straining the neck.

How to Change the Strings on Your 6-String Guitar: LA ARMONÍA

To change your 6-string armonia strings: do it when they look dull or sound dead. Remove and replace them one by one (or a few at a time) to avoid suddenly releasing the tension, winding evenly and downwards on each tuning peg, leaving a little slack, cutting off the excess, and stretching each new string by retuning two or three times. The tuning is standard (E-A-D-G-B-E), so it's easier than with a 12-string guitar.
