La Bella GUI Guitarron Strings

The La Bella GUI strings are designed for the Guitarron Mexicano, the large, deep-voiced bass instrument that anchors the harmonic foundation of every mariachi ensemble. The Guitarron’s massive body and thick nylon strings produce a booming, resonant bass that drives the rhythmic pulse of mariachi music with warmth and power.

These heavy-gauge nylon strings are built to handle the Guitarron’s unique playing technique, where players pluck pairs of strings simultaneously to create the instrument’s characteristic doubled-octave sound. The balanced tension ensures clean, consistent tone across all six strings. Quality Guitarron strings can be hard to find, and La Bella’s GUI set is manufactured to the exacting standards that professional mariachi musicians demand. If you play Guitarron in a mariachi group, these strings deliver the authentic, powerful bass voice your ensemble relies on.
