The JYM80 Yairi Masterworks Jumbo represents the influence of Kazuo Yairi that is heard and seen in every Alvarez guitar. The JYM80 features the FST2 bracing system, a forward-shifted X-brace design that features hand-scooped scalloping to the main braces and asymmetric scalloping to the two tone bars which optimizes string separation, balance and projection. Constructed with a flamed maple body, Sitka spruce top and an ebony fingerboard, the Masterworks Jumbo provides deep, resonant tone and clean articulation. Additional features include a Direct Coupled Bridge for improved sustain and Gotoh tuners.
