The years of the Great Depression were tough sledding for all businesses, and Martin Guitar was not excluded from this. Even though sales were sluggish, the company found a way to sell 11 OM-45 De Luxe models in 1930. With a retail price of $225, which was $45 more than the standard OM-45, the OM-45 De Luxe was a real head-turner. Featuring extra pearl inlay on the pickguard, bridge wings, and bridge pins, the OM-45 De Luxe is now one of the rarest and most collectible acoustic guitars ever built.
