Slated to make their official debuts at Summer NAMM 2018, Yamaha’s two new acoustic-electrics are top-shelf instruments that come in über-exclusive quantities—we’re talking 75 models apiece.

The A4K Limited and AC4K Limited join Yamaha’s A Series as guitars whose bodies are crafted entirely from solid Hawaiian koa. The former is a single-cutaway, dreadnought-sized guitar, while the latter is a smaller concert instrument. They boast the brand’s new scalloped bracing construction, which yields a “louder, richer acoustic sound,” according to Yamaha.

Both instruments are also fitted with Yamaha’s SRT2 pickup system. It lets you reproduce tones from a piezo sound that cuts through the mix to a vintage-leaning timbre akin to recording through either a condenser or ribbon mic. You’re also able to combine both the piezo and mic tones to achieve the tone you’re after.

Besides these highlights, the A4K and AC4K have mahogany necks, ebony fingerboards, double-line abalone fretboard inlays and high-gloss finishes.

Both guitars list for $2,400 and will start shipping in July. For more info, check out usa.yamaha.com.
