Thanks, I'll look into it.
Few questions, tho..
-What's the bass roll-off? Is it needed, or can I go with cheaper batt boxes that don't have it?
-Should I look into binaurals or cardioids?
As far as I know..
Bass roll-off starts cutting some frequencies; you set the limit (for example 100 Hz) and the amount of 'cutting' (examples: 6 dB). Then it double the 'cutting' (in dB) every octave, so you cut 12 dB at 50 Hz and 24 dB at 25 Hz.
A lot of people warn that it's best to cut the frequencies after taping, because if you cut too much, you can 'recover' the lost data; you just need some experience with some PC programmes.
As you're a beginner you should look into binaurals; I'm a beginner too, and with bin. as they are easier to use.
And they are cheaper than cardioid, generally speaking.
If you can solder you should buy some Panasonic WM61-A capsules (digikey and radioshack may sell those) and solder to a earphone cable.. this way you do a nice work with a few money.
There are some tutorials on the net.
