When Martin Guitar decided to change their Dreadnought models to the slimmer, longer 14-fret neck in 1934, the standard was set for the flat-top, steel-string acoustic guitar. At the time, it seemed like every country musician began playing one, as evidenced in the vintage postage postcard collection of these musicians in the Martin Archives. D-18s were a popular choice, but for most guitarists, the D-28 was the model to have. The D-28 models were all great, but there was something extra special about models built in 1937. Maybe the stars aligned perfectly when these guitars were built, but their tone is second to none, and, if volume was what you were looking for, you couldn’t find a better guitar.
