Kang plays mandolin and fiddle with The String Cheese Incident, a Boulder, Colorado–based newgrass/jazz/Latin band. He has a standard acoustic mandolin by Stephen Gilchrist and has owned a variety of 5-string electrics:
In a profile of Kang for Strings magazine, Darol Anger reported that Michael had used one or more instruments built by a fellow named Sean Eaton. It wasn't clear from the article which instrument this was; it could well be one he no longer plays. If you know who built the axe Kang is playing in the photo below, please on the secret.
