Octave-Paired Strings vs Unison-Paired Strings in Mexican Style

Understanding 12-String Guitars: Octave Strings vs. Unison Paired Strings in Mexican Style

12-string guitars have been a fundamental part of the sound of entire generations in genres like folk, rock, and country. But in Mexico, these guitars took on a distinct character, driven by the creativity of local musicians and a very specific need: the lack of access to octave strings.

What are octave strings?

In the classic configuration of a 12-string guitar, the lower string pairs (the first four: E, A, D, and G) combine one string tuned to its natural note with another an octave higher. This creates a bright, expanded sound with a lot of harmonic air. It's the characteristic timbre we hear in bands like The Byrds or artists like Tom Petty.

The Mexican twist: unison paired strings

In Mexico, however, things took a different turn. Due to the scarcity of octave strings in many regions, especially in past decades, musicians began adapting their 12-string guitars by using two complete sets of standard strings, meaning tuning all pairs in unison, without octaving.

This adjustment created a more direct, solid, and uniform sound. Not as bright, but with more body and attack. What started as a practical solution eventually became a distinct style that now dominates the stages of regional Mexican music.

Who uses this style?

This approach is not an exception: it is the norm among the country's great requintists. Figures like Ariel Camacho, Miguel Montoya, Carlos Ulises Gómez, and almost any guitarist of the sierreño, campirano, or romantic requinto genres, use unison paired strings. It is estimated that more than 90% of Mexican guitarists using 12-string guitars employ this configuration.

Karma Guitars' commitment

At Karma Guitars, we understand and value the traditions that define Mexican music. That's why we were the first brand in Mexico to configure our 12-string guitars from the factory with unison paired strings, using two sets of .010 – .047 gauge strings. This adjustment not only respects local customs but also enhances the characteristic sound that Mexican musicians have masterfully developed.

We don't do it because it's trendy; we do it out of conviction. Our commitment is clear: to serve Mexican musicians with tools that reflect their style, their identity, and their sound.
