Sigma Guitar was launched as a sub-brand of Martin Guitar in 1970, marking the beginning of acoustic guitars aimed at a broader audience. Built on Martin's foundational designs and over 180 years of accumulated expertise, Sigma guitars are known for their attractive midrange and bass tones, along with a well-balanced sound. The brand has earned widespread appeal due to its combination of reasonable pricing and quality sound, making it accessible to both casual players and professional musicians.

Sigma offers a wide range of instruments, from all-solid guitars to custom models, catering to various needs. Celebrating its 50th anniversary in 2020, Sigma has become a global brand with explosive popularity across Asia, Europe, and South America, ranking as the number one acoustic guitar brand in Europe. This success highlights Sigma's unique appeal, going beyond its roots as a sub-brand of Martin to establish its own identity in the guitar world.
