As I'm a tribal wind player myself, and Since I'm not western and never play or try orchestral instruments except the sax which I don't have as my own, here's the list of instruments I have.
Klui: there're three sizes of this Thai flute, but I only have two, Klui Lib, the small, high one, and Phiang-o, the medium. I have 5 Klui Lib and 5 Klui Phiang-o.
Seung: there're many sizes and various string patterns of this Lanna lute as well, from small to very large and from two string pairs to three. So far, I have the small and medium two paired ones.
Lanna Ching: my tribal circles. I have one.
Hulusi: originally a historical Tai made instrument and are now Chinese, I have one of these gorgeous reed gourd flute in my possession.
Wot: a Tai-isan pan flute. I have a broken one with me and can't even play it well.
Besides that, I have a yamaha recorder which isn't suppose to be in this list since it's well known, lol.
I plan to collect every instruments I can play, and never hesitate to try others. Who knows, may be one day I'll have my own Kiowa or Anasazi flute.
Why do ghost hunters have to hunt ghosts? Well, there's a fear of being ghosted out there. They may need therapy as well as their ghost hunting kit.
