Slope Shoulder Dreadnought with solid Sitka spruce top, body made of mahogany and Fishman Sonitone Pickup

Presented with the JM-SG45+. Sigma an authentic Slope Shoulder Dreadnought one, which can convince with its powerful sound and its harmonic Vintage optics. The combination of solid Sitka spruce for the ceiling and laminated mahogany for the body promises a dynamic sound with a lively response that will delight both strummers and fingerpickers with powerful bass, harmonious mid-range and brilliant treble.

In addition, a compensated bridge insert made of bone ensures optimum resonance transmission and a flat string position, while the nickel-plated Grover Vintage mechanics keep the tuning clean.

In addition, the Sigma JM-SG45 is equipped with the Sonitone pickup system by Fishman which makes it much easier to pick up the guitar on stage and in the Studio studio. The pickup System convinces with natural warmth and organic dynamics, which do not discolour the sound of the JM-SG45.

The classic Sunburst finish in combination with the Vintage mechanics and the white bindings gives it Slope Shoulder Dreadnought a particularly noble appearance.
