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, it produces bold projection, woody warmth and dynamic clarity, well suited to singer-songwriters and Americana players. Its shorter 24.75" scale length and slope shoulder design enhance playability while adding a distinct tonal flavour.

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+ ideal for players who want their acoustic tone on stage as much as at home. Complete with an official padded gig bag, it's a genuine combination of tone, comfort and vintage style.
