Hand selected materials, handcrafted construction - at an amazing price. With a solid Engelmann spruce top, rosewood body, multilayered mahogany/rosewood reinforced neck, and ebony fretboard, the Yamaha LS6 acoustic guitar can be judged an excellent deal on materials alone. Yet where this concert body really shines is on the strength of its handcrafted construction by expert Japanese luthiers. Every step in the creation of this excellent musical instrument, from tonewood selection to and-sanding the frets, is done in a small factory by master craftsmen. Body top Most manufacturers are using Sitka spruce tops for their high end models. In Yamaha's experience, Engelmann spruce (Canada) naturally suits the role for top woods better than any other. The overriding quality for body top material is an allowance for resonance and Engelmann spruce has this attribute in abundance. It is a light wood that is easy to work and enables a good tone response with a wide harmonic range. Visually Engelmann spruce is comfortable on the eye and its opaque light yellow tint is reminiscent of a mature acoustic instrument. Back & side Yamaha uses rosewood for both the back and sides on all the L series models. The rosewood blends extremely well with the Engelmann spruce top. It disperses resonance evenly and effortlessly. Neck block The neck block reinforces the neck joint. Yamaha has improved the conventional C block design by enlarging the surface area that is in contact with the top of the guitar. The block securely meets the underside of the top adding a real depth to the tone of the instrument. Bracing X-bracing maps out the vibration patterns of the guitar. Each of the eight braces has been carefully positioned in order to bring out the tone in a balanced fashion and find a natural harmony with the guitar's tone woods.
