African Mahogany is a harder wood than spruce or cedar. Harder woods will have a break-in period where they are brighter when you first get the guitar and, as they are played, they mellow out and you’ll notice more of the deeper tones. Volume levels seem to be on par with spruce tops but with less attack.
The dreadnought body shape has been the most popular shape for decades now for a number of reasons. First, it has a nice balance between low, mid and high frequencies. Where some body shapes scoop the mid range, a dreadnought will bring the mid range up. This is important when playing with a group of instruments. The mid range of a guitar will stand out. Because of the tonal balance of a dreadnought, the sound does not get muddy and will be very articulate even when a player is a more aggressive picker.
