About this Product
This clip will fit a Naiant X-X microphone (or other same-size mic) to the headjoint of an Irish flute with a 27mm diameter. YMMV and I make no warranties of any kind. It's up to you to decide whether you're worried about it potentially scratching your flute or microphone. The mic opening is cut with a 9mm diameter and the flute opening is cut with a 27mm diameter. If you would like one to fit a different instrument or mic, contact me with the measurements as precisely as you can manage. It is based on McGee's "Great Australian Bight Clip": http://mcgee-flutes.com/mic-clip.html
