I'm just wondering what type of modification can you do to a $150 condenser microphone to make it sound like a $1000 microphone? What does it do to the frequency response curve, signal to noise ratio, top signal pressure level or open microphone voltage?
It's actually a $68 mic...

But if you understand the anatomy of a mic, specifically a condenser mic, there is ALOT you can do to modify them that will drastically improve the sound.
With these mods, the mic functions at its optimum.
What does it do to the frequency response curve, signal to noise ratio, top signal pressure level or open microphone voltage?
That’s assuming that all of those attributes you stated are faulty to begin with. Have you ever tried a Stock V63m before? Its a fine mic to begin with, but is not a "Great" mic.
It actually already has a great capsule to begin with, doesn't really need to be changed. However, if you understand the circuitry of the mic, there is a few things that could definitely be improved.
I don’t know if you are familiar with Guitar Effect Pedals. However, the same principles apply. You see, a $29 Guitar Center Special distortion pedal that sounds like crap doesn't HAVE to sound like crap.
If you understand the schematic, and can see what changes need to be made done, With a few components change, few transistors here, couple high quality capacitors there, and Voila, you have a pedal that can keep up with a boutique $200 Box.
However, I do not do the Mic Modifications myself...yet. I have someone do it.
Peace
