SIGMA GUITARS Series Se Gjme

A Grand Jumbo Designed for Power and Versatility at Sigma

With the GJME, Sigma relies on a folk lutherie classic: the Grand Jumbo format, appreciated for its volume reserve and ability to "fill" the sound space. Within the range, this model clearly targets musicians who want an expressive acoustic in natural playing, while maintaining the practicality of integrated amplification to easily transition from living room to stage.

For Which Guitarist and Styles?

The Sigma GJME is especially aimed at motivated beginners to intermediate guitarists looking for a comfortable and inspiring guitar, but it will also appeal to experienced musicians seeking a reliable instrument for accompaniment. The Grand Jumbo size highlights folk, pop, country styles and anything based on pick-driven rhythm. In fingerstyle, it retains good clarity, with a solid low-end foundation that adds body to arrangements.

The Sound

The solid Sitka spruce top delivers a lively and nuanced response: the attack is clear, harmonics rise easily, and the guitar handles differences in intensity well between light playing and strong strumming. Combined with the Grand Jumbo format, this results in generous projection and an immediate sense of power.

The mahogany back and sides complete the sound with a warm signature: present mids, rounded lows, and balanced tone, ideal for supporting vocals. The bone components at contact points (nut and bridge area) promote efficient vibration transfer, with clean sustain and pleasant articulation. Plugged in, the Sigma EQ with built-in tuner allows quick control of your tone and tuning, a real advantage in rehearsals and on stage.
