Sigma SDM-18 Dreadnought Acoustic Guitar Inc Sigma Embroidered Hard Case


Sigma SDM-18 comes with all solid tonewoods, Solid Sitka Spruce top and Solid Mahogany back and sides, Ebony fingerboard and bridge complete the high spec. This guitar is in as new barley used condition. Read the reviews, this guitar would not disappoint if it had a more famous brand name on the headstock!  Comes with a high quality Sigma Embroidered Hard Case.

The SDM-18 takes inspiration from one of the most definitive dreadnought guitars in the world: the D-18. Combining all-solid tonewoods with the classic dreadnought design has resulted in one of Sigma’s most resonant, powerful guitars – a massive sound that far outweighs its modest price point.


The SDM-18 has a responsive, powerful tone that you’ll seldom find in a guitar at this price point. Solid Mahogany back and sides provide plenty of low-end warmth and projection, perfect for big strummers and studio sessions alike.

For the top wood, Sigma have opted for Solid Sitka Spruce – an acoustic classic. Spruce is known for its balanced, up-close sound. Combined with the Mahogany construction, you’ve got a tonal palette that’s as broad as a dreadnought gets.


For the neck, the Mahogany theme continues. This ensures that the SDM-18 rings true from headstock to bridge, with a dynamic, responsive sound that’ll suit flatpickers, fingerpickers and everyone in between. Combine this with Sigma’s trademark attention to detail and you’ve got a guitar that punches way above its weight.
