USED C.F. Martin / D-45 Standard, 2021, Natural [12]

We’ve just received a used, high-quality example of the D-45—Martin’s flagship model and the guitar everyone dreams of owning.
This 2021 model of the D-45—which, as is well known, has established an unshakable reputation as the pinnacle of Martin acoustic guitars—is now in stock.

It features exquisite wood materials: a spruce top with a beautifully even grain, sides and back crafted from carefully selected East Indian rosewood, a straight-grained mahogany neck, and a jet-black ebony fingerboard.

While there are minor differences in specifications compared to models from 2025 onward—such as the bracing, bridge shape, neck shape, neck volute, heel shape, nut angle, and fingerboard edge—this model still allows you to fully enjoy its gorgeous appearance and superb tone.

It features forward-shifted X-bracing, delivering the rich bass, powerful volume, and sustain characteristic of the D-45.

It shows minimal signs of use—just a few minor scratches—and is in excellent condition.
An endpin has been installed, and the instrument has been fully serviced and cleaned at our repair center, ensuring excellent playability.
