I realize that this is a rarefied part of the music scene, but I'd thought to ask.
My didge is a pine didgeridoo with a padauk/bloodwood mouth piece, pitched about D.
It's so cool to see someone ask that :o
I do not play didgeridoo but I can produce an imitation of the sound with my voice. I can also produce a practically perfect impersonation of a slide whistle.
