Re: Polar pattern mysteries...

I'm tempted (that is to say planning) to add a 'multi-pattern tube mic'
to my collection and, until just now, was mystified as to how a mic like
this one:

...could provide the various patterns (with in-between settings, it
appears) simply by fiddling with the power supply?? Anyway, a bit of
Googling has cleared this up (to a point) with information like this...

Now the questions are: Is there any downside? Are there any reasons to
avoid these 'dual/variable capsule' arrangements? (Especially at the the
lower price point of these cheerfully cheep chinky chappies, or is it
like everything else from the Land Of The Noodle - if the basic
principle is sound, one takes one's chances, sucks it and sees...??)

The alternative is to stick to a straightforward cardioid design like
this one:

Suggestions/caveats welcome....



Ermm.. All this recording gear.. When's our Keith going to have his
mobile recording wagon on the road?..

Perhaps it could go on the side of the motahbike;)...
