Interesting, I didn't know this. Many guitar amps also have a "Line level"
output jack. Are these jacks actually line level?

Do these do much more than some frequency filtering? Can't help but
think this would be just as easy (read: cheaper) to do in software...

I'm curious as to the necessity of the impedance-matching transformer.
I use a Sony dynamic mic (sorry, don't remember the model number) and
plug it straight into my soundcard's Mic in jack and don't hear anything
bad I wouldn't expect to hear from a soundcard's Mic pre. What am I
listening for and what's the difference?
(of course it's possible that my SBLive's Mic pre and ADC are so bad
that it wouldn't make a bit of difference ::-)

Most of the threads I've read on r.a.p go like:
if (cost < 350)
return "Sucks!";
else if (cost < 500)
return "Not so bad";
else if (rand () < (RAND_MAX / 2))
return "Good";
else
return "Sucks!";
