Martin OM-45 Acoustic Guitar (2025)

Martin OM-45 — The Pinnacle of Ornate Craftsmanship

The Martin OM-45 is one of the most exquisite and coveted acoustic guitars ever produced — a true heirloom instrument that represents the very apex of Martin's legendary craftsmanship. Originally introduced in the 1930s and revived in the Custom Shop era, the OM-45 is defined by its breathtaking abalone inlay work, premium tonewoods, and the balanced, articulate voice that has made the Orchestra Model a favourite of fingerstyle players and discerning collectors worldwide.
