Sigma GMC-STE+

w/ Fishman Isys+ preamp and tuner


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.
