Sigma's GMC-STE is an extremely versatile grand-sized electro-acoustic for players who need a guitar for a wide variety of genres. Boasting a rich tone and clarity, this guitar is perfect live or at rehearsals. 

Detailed tones

Sporting a Mahogany body and Spruce top, the GMC-STE produces warm tones and projection for an array of styles such as light fingerpicking or heavy strumming. A real bone nut provides great sustain for those vast open chords. The large cutaway grants access up to 14 frets for lead playing. The satin neck is a nice feature for easy movement up and down the Micarta fretboard.

The built-in Fishman Isys+ EQ is perfect for hooking up to an amp on the fly, so plug in and play live or at rehearsals quickly and without too much fiddling, especially on an unfamiliar amp's EQ channels. The GMC-STE+ also comes with an inbuilt tuner, great for live performances or any moment you need to pick up and play without the fuss of digging out the one you lost down the back of the sofa.

More info about this Product

Acoustic Guitars

Acoustic guitars produce their sound naturally through the vibration of the strings and body, offering a direct and expressive playing experience. They come in a wide range of styles, including steel string and classical designs, each with its own feel and tonal character. Body shape, wood choice, and construction all influence warmth, projection, and balance, making acoustics suitable for everything from gentle fingerstyle to confident strumming. Whether used for songwriting, practice, or performance, acoustic guitars provide a simple, honest connection between the player and the music.

Electro-Acoustic Guitars

Electro-acoustic guitars combine the natural sound and feel of an acoustic guitar with built-in electronics for amplification. Fitted with pickups and preamp controls, they allow you to plug directly into an amp, PA system, or recording setup while retaining an acoustic character. They’re ideal for live performance, rehearsal, and home recording, offering volume control and tonal adjustment without relying solely on microphones. Electro-acoustic guitars suit players who want the warmth and responsiveness of an acoustic instrument with the flexibility to play amplified when needed.

Guitars

Guitars cover a wide range of instruments designed to suit different styles, techniques, and sounds, from acoustic and classical models to solid body, semi-hollow, and hollow electric designs. Factors like body shape, scale length, neck profile, string type, and pickups all influence how a guitar feels and responds, making each type suited to different players and musical approaches. Whether used for rhythm, lead, songwriting, or experimentation, guitars are expressive, versatile instruments that form the heart of countless genres and playing styles.

Electro-Acoustic

Electro-acoustic guitars are acoustic instruments fitted with built-in pickups or microphones that allow them to be amplified or connected directly to a PA system or amplifier. They retain the natural acoustic tone and feel of a traditional acoustic guitar while adding the convenience of onboard electronics.

They are commonly used for live performance and recording, especially in situations where consistent volume and clarity are needed. Electro-acoustic guitars often include controls for volume and tone, and sometimes built-in tuners, making them a practical choice for gigging musicians who want an acoustic sound with modern flexibility.
