The Sigma 000MC-15E acoustic guitar is a traditional 'orchestra' with modern appointments like a cutaway to play the upper frets, and a Fishman pickup with tuner for amplified playing. The sound of this guitar is warm and rich, and the playability is just fantastic.
The SIGMA brand was launched in 1970, and have since established an excellent, even legendary, reputation. Some models were said to be of outstanding quality, both, in construction and sound. Most owners still swear by their instruments and would never part with them.
