SIGMA GUITARS Jmsg45

A Modern Slope Shoulder, Between Traditional Dreadnought and Smooth Playability

With its "Dreadnought Slope Shoulder" profile, the JM-SG45 fits within the spirit of bold acoustic guitars while remaining comfortable to hold. The combination of solid spruce and mahogany aims for versatile balance: enough body to accompany, and sufficient precision to highlight attacks and rhythmic placement.

For Whom and Which Styles?

The JM-SG45 is well suited for serious beginners to intermediate guitarists seeking an expressive acoustic, as well as for stage musicians looking for a simple and effective electro-acoustic. Its dreadnought format makes it particularly comfortable in folk, pop, country, acoustic rock, and pick accompaniment, while remaining responsive to fingerpicking.

Sound

The solid Sitka spruce top provides clarity, good volume reserve, and a response that opens up over time. The mahogany back and sides promote a direct sound with present mids and a warm grain, ideal for rhythms that "carry" in a mix. The bone nuts help transmit vibrations with greater precision and contribute to a clear sustain. Finally, the slope shoulder format slightly softens the attack compared to a more angular dreadnought, resulting in a tone that is often rounder and more singing.
