Sigma OMM-ST OM Acoustic Guitar Matt Finish 13/4" Nut in Natural


You'll love this if you play finger picking styles!

Firmly establishing themselves as a guitar manufacturer offering very high-quality acoustic guitars at an extremely humble price Sigma now bring you the OMM-ST Acoustic Guitar.

Superb playability and excellent build-quality make the OMM-ST a go-to guitar for all you players who love to feel a top-quality guitar at a very convincing price! You'd expect to pay a lot more for an acoustic of this standard if it displayed another brand logo on the headstock, but don't be fooled, Sigma know what they're doing!

Space to play
You already know that you're getting a top-grade guitar here, showcasing the fluid playability and comfort of a guitar that would normally cost you so much more from another manufacturer. Its body shape feels comfortable and lightweight in your arms, which limits the risk of back ache when you play for longer periods. Finger pickers will also appreciate the 13/4" scale nut, giving the strings a wider distance, ideal for folk genres and picking styles that require space for articulate playing.

Crystal Clear
The Solid Sitka Spruce top and Mahogany back and sides produce a clear and punchy tone, full of warmth and organic acoustic flavour. Its classic 000 body shape ensures your playing boasts natural resonance, perfect for guitarists that play live, making sure they're heard when they're mic'd or are just playing unplugged.

Simply does it
Simplicity is what the OMM-ST is all about. Stripping away any unnecessary detail you're getting a guitar that really knows what's important in an acoustic instrument, the tone and feel! The Solid Spruce top really pops when contrasted to its Mahogany back and sides, while its lack of binding give a minimal style that players who appreciate a less-cluttered look will love. The matt finish makes the OMM-ST a natural looker and doesn't need any frills to help it look great!
