Rich, Resonant Acoustic Tone

The solid Sitka spruce top provides a responsive, articulate sound with plenty of dynamic range. Paired with mahogany back and sides, it produces a warm, rounded tonal character that works beautifully for everything from folk and country to rock, blues, and singer-songwriter performances.

The slope-shoulder dreadnought body delivers a strong, full-bodied voice with satisfying bass response and plenty of volume, making it an excellent choice for both solo playing and accompanying vocals.

Comfortable Playability

The mahogany neck features a low-profile shape designed for a comfortable playing experience. With a 24.75-inch scale length and a 1-3/4-inch nut width, the JM-SG45 offers a distinctive feel suited to chord work, expressive strumming, and detailed fingerstyle playing.

A bone nut and saddle contribute to the guitar's natural resonance and sustain, while the Micarta fingerboard and bridge provide a smooth, dependable playing surface.

Ready for Amplified Performance

Equipped with the Fishman Sonitone pickup system, the JM-SG45 is ready to connect to an acoustic amplifier, PA system, or recording setup. Its onboard electronics make it a versatile option for rehearsals, live performances, and studio sessions while retaining the character of its natural acoustic sound.

Vintage-Inspired Sunburst Finish

The polished gloss Sunburst finish gives this guitar a classic, eye-catching appearance. Complemented by open-gear Grover nickel tuning machines and elegant ivoroid-style tuning knobs, the JM-SG45 delivers a refined vintage look that stands out on stage or in your collection.
