I have some nice acoustics with spruce tops, but I was looking for something with a warmer, deeper tone. This martin was the perfect choice. All solid mahogany, back and sides. The tone is rich and deep, and the sustain lasts forever. I especially like the rosewood neck when I dig into the guitar. It also has special vintage style open tuners from Grover. The guitar comes in a natural brown finish, but I opted for this beautiful matte finish sunburst color. What's not to love about this guitar.
