The woods, sound and suitability of the Sigma GMC-15E Western Guitar:

The Sigma GMC-15E Western Guitar is a universal all-round instrument. Thanks to a solid mahogany top and a mahogany body, this Grand Auditorium body resonates with clear basses, well-defined, warm and nuanced mids and shimmering highs. Accordingly, the Sigma GMC-15E Western Guitar is suitable for many different music styles and finger pickers and bluesers will particularly appreciate the warm and assertive mids. At the same time, chrome-plated Grover tuners ensure tuning stability and precise tuning, and with the cutaway, playing in the higher registers is also possible without problems;

The Fishman Isys+ of the Sigma GMC-15E delivers the transparent sound for the stage

The Fishman Isys+: Small pickup, big effect

The Fishman Isys+ has a lot to offer for a relatively small pickup. Accordingly, in addition to the 2-band equalizer, with adjustable bass and treble, a phase knob is already integrated, which ensures significantly less feedback susceptibility in the stage situation. With the volume control the volume can be adjusted and the built-in tuner delivers the consonant sound in every situation. A battery indicator lights up when the battery is low and gives the information to change. All in all, the Fishman Isys+ delivers a dynamic and transparent amplified sound;
