Gianni,

That's an interesting question. Theoretically if you blank off the rear, it=

will disable the fig-8 element of the cardioid pair and produce an omni-ish=

response. It works on small cylindrical type end-on csrdioid mics but the
frequency response may be a bit odd with a side-on type mic.

You can't do this electrically inside the mic as the common output of the
omni and fig-8 elements is the single shared semi-perforated backplate. Mic=

diaphragms are normally grounded to prevent electrostatic pickup.

Try it with a few layers of 2" gaffer tape using a piece of tissue to keep=

the sticky off the mic. An elastic band will hold it in place. Let us know=

what the modified polar pattern sounds like.
