The Martin D 45 acoustic guitar is one of the most beautiful acoustic guitars in both sound and appearance that has ever been made. Now, I've never owned one, but I've played more than one. Basically, the D 45 is just a D 28 that has a lot more mother of pearl, or abalone inlay, and some gold plating on the tuning keys. It's a wonderful instrument, and is a very safe investment.
