Frequently Asked Questions

The OM-28 uses higher-grade woods, resulting in a more complex and resonant tone; the OM-21 is slightly more focused and direct, with a bit less low-end warmth.
The OM-21 features a comfortable modified low oval 'C' shape neck, which should suit most hand sizes, but those preferring a flatter profile might find it a touch full.
It's a gloss finish that provides a beautiful aesthetic, but it’s not as thick as some older Martins, so care is needed to avoid scratches and dings.
