Radioshack PZM microphone?

The stuff for the Radio Shack PZM mics is quite old and the mic is no longer made. You would have to find a used one to mod.

This article above seems to say that mods can be done to one of the newer "business Mics" by RS, but it's seems a very different mic than the old PZM mics they used to make.

Here is a link to a text file containing several mods: http://www.itrstudio.com/pzm.txt
 
They also had those cheap piezos for building triggers some years ago. A shame they wouldn't ship them worldwide, I would have ordered 20 of them at $1.50 each.
