The guitars of the Keystone Series are the working musician's best briend. The Dreadnought is the keystone of the acoustic guitar world - metaphorically speaking. That's why Takamine named this family of traditional (and not-so-traditional) Dreadnoughts the Keystone Series. Every one of these Dreanoughts starts with a hand selected solid pruce soundboard, voiced to classic Dreadnought perfection. Add your choice of back and side woods and you've got an instrument that's ready for any stage or studio.
