Independent shopping perspective
The Korena take
Finished in black gloss, this Custom Shop 18 Style OMC is a right-handed acoustic with a spruce top, mahogany back and sides, and an OM orchestra model body. Scalloped X bracing supports the clear, responsive character described for the instrument, with mahogany adding warmth and vintage-minded midrange detail. The modified low oval neck has a satin finish, and the ebony fingerboard features scalloped diamond inlays in red pearl and mother-of-pearl. Grover gold vintage-button tuners and a hardshell case round out the build.
Strong match
Who this is for
- Fingerstyle arrangements that benefit from the OM body’s focused, articulate voice.
- Dynamic strumming where balanced response and clear note definition are useful.
- Studio, stage, or home acoustic sessions calling for a spruce-and-mahogany OM guitar.
Consider the trade-offs
When to look elsewhere
- Amplified setups requiring onboard electronics; this is listed as an acoustic guitar.
