Western Red Cedar is a softer wood that has great warmth. Because of the warmth of cedar, it pairs very well with the human voice and is great for singer/songwriters. Cedar naturally amplifies quieter playing styles and is a favorite of fingerpickers.
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.
