Sorry for this budget-question, but how useful is the boundary ('PZM') mic that Radio Shack has for US$39.99 ?
It's the Optimus #33-3022.
Since someone here will be visiting the US soon I was thinking about asking him to get me a pair.
Applications will mostly be for loud sources, like room for drums or guitars.
(Will add the 'usual' PZM-mods)
Any good ? At least usable ? Or just a cheap mic with a bad capsule ?
