Yamaha AC4K Solid Koa Limited Edition 39/80

The Yamaha Limited Edition All Solid series offer a collectors grade instrument in a performers budget. This series offers some of the most visually stunning tropical timbers ever seen in this price range.

This is the Yamaha Limited Edition All-Solid Koa Wood Ac4K Concert Acoustic-Electric Guitar. Koa is a dense, tropical hardwood that combines an incredible midrange focus and top-end brightness, along with great midrange overtones, warmth and sweetness to the voice.

The AC4K is an ideal fit for the experienced guitar player looking for an instrument with a high degree of playability and a versatile sound for stage and studio.

Additionally, the alternative tone woods, fine-grain patterns and incredible look of the instrument will appeal to collectors. This new model features standout sound quality and craftsmanship that is untouchable at this price.

The AC4K Concert features an all-solid Koa top, back and sides, imparting a dark and exotic look and feel to the guitar.

Cutting-edge acoustic analysis technology developed by Yamaha led to the development of these models’ new scalloped bracing pattern for the top board and shorter bracing than normal for the back board. The result is overall increases across the lower range, richer harmonic overtones in the midrange, with louder and stronger low-mid ranges.

The SRT2 pickup system, also developed by Yamaha, perfectly suits the guitars for versatile acoustic-electric performance. The clear sound of the piezo pickups is ideal for cutting through a dense mix, and for lush detailed resonance, the pickup system also provides studio-grade microphone emulations culled from a select handful of vintage studio condenser and ribbon mics.

The guitar’s tone can be customised by mixing piezo and mic tones to find the optimal sound for any playing style. The system controls also include volume, treble and bass control knobs; the last doubles as an auto-feedback reduction button.
