Overview: Like koa, walnut’s density and stiffness yield bright treble notes, but with a more present midrange that splits the difference between rosewood and mahogany. The bass tones initially produce a woody character that will grow richer with time and extended play.

Origin:  USA

Sound: Another beautiful hardwood, walnut has a similar density and stiffness to koa, with a similar tightness initially. Like koa, it tends to have a bright top end, but with a more present midrange, somewhere between mahogany and rosewood. Walnut also starts off a little deeper on the low end, initially giving it a slightly woodier sound than koa. The low end will continue to fill out after being played in.

Goes Well With: Players who like a blend of brightness, projection and warm overtones. A smaller-bodied walnut guitar with a cedar top would likely appeal to fingerstyle players, while flatpickers and strummers on a larger body with a spruce top will find ample horsepower, low end and crisp highs to support an aggressive attack.
