When most folks come across anything that's been marked by fungal rot they throw it right in the garbage. Ibanez makes an instrument out of it. E.g. this thing and also the Ibanez UEW20 Acoustic Electric Concert Ukulele — the place where spalted mango tree wood goes if it's lived a just life.

The Ibanez UEW20 Ukulele (or UEW20SGE-3T-01 i it's being announced at a formal dinner) isn't a mere looker; it's got a sweet-yet-articulate unplugged tone and a simple-yet-effective on-board preamp for crafting the amplified uke tone you always dreamed about. . . or that you startled awake in a pool of your own sweat from, whatever you're into.
