I've never had an instrument made of mango but I adore the looks of that particular wood when it's figured (or flamed in the pics above). For example, the Romero Creations ukes made of mango look brilliant. The issue for me is that the tone just often isn't quite there. Many brands that make mango ukes also make the same models in koa whose tone I much prefer over mango so it's hard for me to justify getting a mango uke.
I generally like the tone of mango, but at the same time, I prefer loud volume, which mango doesn't always seem to give. Case in point, my Pono mango pineapple has a beautiful tone, but is on the quiet side. Although my experience with Pono is that they aren't particularly loud ukes, so maybe it's the construction.
Similarly, I recently went back and listened to all the HMS sound samples of Romero Replicas on Vimeo, just to hear the differences in their tonewoods. I found them to be mostly similar--it helped that it was the same song and setting/set up for most of them. That was for the koa, spalted mango, spruce/mahogany, and all mahogany. I did find the spruce/acacia and the walnut models to sound the most different, though they're also played in different settings with different songs by a different person.
My experience with mango so far: the tone of the Pono pineapple was better (to my ears) than other Ponos. But like those other Ponos, on the quieter side. I might put that one up for sale. Romero's Replica in mango seems to sound very similar to other Replicas (and have decent volume). For Rebels, their mango has both decent volume and a great tone--in fact, when I was researching Rebels, I found that most people seemed to prefer the mango to their spruce/mahogany, although I think my preference is the other way.
