The Sigma GJM-1E-MFBK is made of high-quality wood and has a stunning design.

Solid Sitka spruce top and laminated mahogany body.

Solid Sitka spruce top

The guitar’s core tonal strength comes from its solid Sitka spruce top, one of the most respected tonewoods for acoustic clarity and resonance. Known for its bright, detailed sound and strong overtone response, it delivers both dynamic range and note definition. The laminated mahogany back and sides enhance the tonal palette with warmth and midrange richness, making the GJM-1E-MFBK a versatile acoustic all-rounder across genres—from folk and country to pop and rock.

A pleasantly playable mahogany neck.

Compact mahogany neck

Designed for extended sessions, the mahogany neck features a low-profile carve that fits naturally in the hand, reducing fatigue and supporting smooth transitions across the fingerboard. The 44.5 mm bone nut provides ample string spacing for accurate fingerpicking and powerful strumming, while chrome die-cast tuners ensure precise tuning and long-lasting stability.

The professional Fishman Presys II pickup system.

Fishman Presys II

With a built-in Fishman Presys II preamp system, the Sigma GJM-1E-MFBK is fully equipped for live performance and studio recording. This system delivers a natural, uncolored sound and features intuitive onboard controls, including volume, bass, and treble EQ. An integrated tuner allows quick and accurate adjustments between songs, ensuring that you stay in perfect pitch – whether on stage or in rehearsal.

The unique finish creates a magical sparkle.

Metallic Flake Black finish

The most eye-catching feature of this model is its Metallic Flake Black finish, which shimmers under light for a look that is both elegant and edgy. This unique visual aesthetic celebrates players who embrace individuality and aren't afraid to stand out. Whether you're performing live, recording in the studio, or simply practicing at home, this guitar turns heads while delivering authentic acoustic tone.
