They say mahogany produces a soft, sweet, and mellow tone... and they say the same for mango!
Mango and mahogany originate from a completely different family with different grain directions, which makes me somewhat skeptical of the dearth of comments currently out there--often mixed. From what I read, they sound similar, but I also read that mango has a bright tone like koa. Koa similar to Mahogany similar to Mango similar to Koa? Well, I guess it makes sense why people buy these ukulele woods so frequently.
Tony Graziano says mango is "similar to mahogany though a bit harder." So far, that's the only thing I've heard from any distinguished persons. For now, I'll just go off the assumption that mango keeps "the ukulele sound" well enough for anyone to enjoy. That's probably all anyone needs to know anyway.
Sorry, ichadwick, but your posts I read the various ukulele forums seem a little too overanalyzed. =P Don't get too caught up out there. LOL
