Like the pinnacle of the Teton mountain range, this guitar is the pinnacle of the Teton Guitar brand. We took all the things people loved about our STS105NT and upped our game. This guitar has an all solid body. Solid Western Red Cedar for the top and African Mahogany for the back and sides. The companionship of cedar and mahogany is a dream come true to singer/songwriters. The blending of tones produced by both wood types accentuates the human voice.
