SDR-28
Ships from our warehouse. No store pickup available for this item.
The Sigma SDR-28 is a traditional dreadnought that pairs classic tonewoods with refined craftsmanship for a bold, full-bodied sound. With a solid Sitka spruce top and solid Indian rosewood back and sides, this guitar delivers outstanding projection, crisp articulation, and lush sustain — ideal for flatpickers, singer-songwriters, and rhythm players. Its square-shouldered dreadnought design ensures a familiar feel and room-filling resonance that holds its own in any setting.
A low-profile mahogany neck and jet-black ebony fingerboard provide a smooth, responsive playing surface, while bone nut and saddle maximize sustain and tonal clarity. Premium appointments include Grover open-gear tuners, tortoiseshell pickguard, multi-strip purfling, and a gloss finish with aging toner for a timeless aesthetic. The SDR-28 blends power, tone, and vintage style into an instrument that rewards every note played.

We endeavour to show the actual instrument in stock whenever possible, but the guitar in stock may differ slightly from the one shown on our website. Materials used can look different from guitar to guitar, including timber grain and colour, parts colours and finishing. If an instrument is a one-of-a-kind or preowned guitar, the picture will always be of the actual guitar in stock, but production models may have slight variations to the picture shown.
If you're after a particular look, feel free to email us at info@acousticcentre.com.au or send us a message through our chat service to request photos of the actual guitar in stock. We are more than happy to send through pictures of all in-stock guitars, to make your choice easier.
Please note that returns will not be accepted for variations in timber grain / colouring, finish variations and parts colouring, unless there is a fault with the instrument.
