Mahogany is one of the most popular choices of tonewoods for ukulele backs and sides, though it’s also used as a top material. Mahogany is a dense wood, with a dark finish, and close grain. Tonally, it has far warmer, darker tone than both Cedar and Spruce.
As a material for back and sides, mahogany’s density can add great ‘punch’ and projection, adding warmth, but with definition, and a ‘woody’ character.
The combination of spruce and mahogany is one of the most popular, because it offers a tone that sounds very balanced, yet versatile, lending itself very well to many musical styles.
