A.R.E. (Acoustic Resonance Enhancement)A.R.E. (Acoustic Resonance Enhancement) is an original wood reforming technology developed by Yamaha. . Through precise control of temperature, humidity, and atmospheric pressure, the molecular properties of the wood can be manipulated into a more acoustically ideal condition, similar to the molecular characteristics of woods in instruments that have been played for years.New Designed Bracing PatternA modified non-scalloped bracing design retains the L series’ characteristic bright tone while enhancing low-end tone. High Comfortable Traditional Neck ProfileA reevaluation of string spacing, string height, fingerboard binding, and neck taper led to a new neck shape that better fits today’s raditional players. The new design offers stable grip and smooth playability over the full length of the neck.5-Ply NecksNew 5-ply neck designs are constructed of rosewood and mahogany plies. The design integrates the neck, head, and body into a single unit creating a powerful, rich sound. This approach also creates a strong, stable neck that resists twisting and warping.LL BodyThis traditional Yamaha body style is known for its rich volume, a wide dynamic range, and excellent tonal balance. Beautiful, transparent tone is the result of a design that has been refined by artists around the globe.
