In the late 1960s, American guitar manufacturers faced significant competition from affordable Japanese-made guitars that closely resembled American models, which threatened their market dominance. To counter this, American companies launched “Sigma Guitars” in 1970. These acoustic guitars were built by skilled workers in efficient Japanese factories and then inspected in the US before being sold. Sigma Guitars quickly earned a reputation for their exceptional quality in construction and sound, attracting a dedicated fan base and collectors. Today, second-hand models are rarely available as owners are reluctant to part with them.

Introducing the Sigma SG Series, renowned for its unique design and superior craftsmanship. Each guitar features a select solid spruce top, ensuring excellent sound quality and durability. The series includes extravagant pickguards and other fine attributes that showcase Sigma’s commitment to excellence. Every guitar in this series is equipped with pickup systems and strung with D’Addario strings, providing a perfect blend of acoustic and amplified sound.

The Sigma JM-SG45 is a standout model in the SG Series. It boasts a D-14 fret, slope shoulder body size, and a solid Sitka spruce top, which contribute to its rich, resonant tone. The mahogany back and sides, along with a low-profile mahogany neck, offer a comfortable playing experience. High-quality components like the bone nut and saddle, micarta fingerboard and bridge, and Grover nickel open-gear tuning machines with ivoroid knobs ensure reliability and precision.

Additional features of the Sigma JM-SG45 include a two-way truss rod for easy neck adjustments and Fishman Sonitone electronics for excellent amplified sound. The guitar comes with a polished gloss finish in sunburst and a softshell case (SSC-D) for protection. With D’Addario EXP16 strings, the Sigma JM-SG45 is ready to deliver exceptional performance right out of the case.

SG

The Gibson SG (Solid Guitar) is a rock icon with attitude. Introduced in the early 1960s, it took the Les Paul’s power and gave it a sharper, lighter, double-cut design for faster access to higher frets. Its twin humbuckers deliver raw, biting tone and endless sustain — perfect for everything from blues to heavy rock. Played by legends like Angus Young and Tony Iommi, the SG proves that simplicity, style, and sheer power never go out of fashion.
