Sigma SJM-SG45+ All-Solid Slope Shoulder Dreadnought Acoustic Guitar

The Sigma SJM-SG45+ is a vintage-inspired slope shoulder dreadnought that delivers rich, powerful tone and standout craftsmanship. With a solid Adirondack spruce top and solid mahogany back and sides, this guitar produces bold projection, woody warmth, and dynamic clarity — perfect for singer-songwriters and Americana players. Its shorter 24.75” scale length and slope shoulder design enhance playability while adding a distinct tonal flavor.

This upgraded model features a traditional sunburst finish, Grover open-gear tuners with ivoroid knobs, and premium tonewood appointments like an ebony fingerboard and bridge. The LR Baggs Element VTC pickup system delivers studio-quality amplified tone with onboard volume and tone controls, making the SJM-SG45+ just as ready for the stage as it is for the living room. Complete with an official padded gig bag, it’s a stunning combination of tone, comfort, and vintage style.
