Cameron,

Is it a static electricity shock?  Do you get one short shock and then you can 
hold the mic?

Hi.  it happens with dynamic and condenser mics, and even when the phantom
power is off for the condensers.

plastic mic clips being used since I only have small diafram condensers at
present.

Remember static electricity with carpet?  Also, is the mic condenser with 
phantom power or dynamic?  In either event is the mic mount a spider mount, 
or, just one which you screw onto the boom?  It's probably plastic, but I'm 
wondering if there is a grounding problem, if the mic and stand are breaking

or floating the ground?

Nick
