The D-45 holds a special place in many guitar players’ hearts and is thought of by many as the pinnacle of what an acoustic guitar should be. With only 91 examples being built before the model was discontinued soon after the United States’ involvement in World War II, a pre-war D-45 is arguably the most collectible acoustic guitar ever built. The limited quantity, along with the fact that these guitars produce amazing volume and tone, results in sales prices well into six figures whenever one comes to market. The model that lives in the Martin Museum, often referred to as the holy grail of acoustic guitars, is number 80 out of the 91. It exhibits all of the great qualities that are so coveted in these guitars.
