Yamaha Guitars A4K and AC4K

For fans of koa who are not fans of the typical price of admission for an all-koa instrument, Yamaha Guitars might have you covered with the A4K and AC4K debuting here at NAMM. Both the dread and concert-size guitars feature the revered tonewood for the top, back, and sides, and also boast scalloped bracing and Yamaha's SRT2 pickup system that has a built-in auto-feedback button. With an MSRP of $2,400, Yamaha contends these A Series instruments are the only all-koa guitars on the market for less that $3,500. Solid.
