Yamaha has launched the A4K and AC4K, building on their A Series line of acoustic-electric guitars with the only solid-Koa guitars under $2,500.
The guitars are 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. The new models feature standout sound quality and craftsmanship that is virtually untouchable.
The concert-size companion AC4K features an all-solid Koa top, back and sides, imparting a dark and exotic look and feel to the guitar. A dense, tropical hardwood, solid Koa combines an incredible midrange focus and top-end brightness, along with great midrange overtones, warmth and sweetness to the voice.
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.
Crafted from all-solid Hawaiian koa, the AC4K features the A Series small cutaway body, double-line abalone inlays, unique black tuning machine keys together with specially recorded mic models on the SRT preamp for plugged-in tone that matches the acoustic sound.
