I figure this is just another way to get people to click your link, but let's entertain it for a second.
Your post comes across as being from someone quite far up the ladder.
"Listen up, newcomers....here are some time honoured studio secrets" kinda thing.
If you happen to be just rapping over a beat that someone else made and you bought/borrowed/took/whatever, it might be worth pointing it out.
A more appropriate title in that case would be how to get professional vocal recordings for $150 dollars.
It's still gonna be tight though.
Essentially what you're telling us is how to eq vocals to sit well in a pre studio recorded backing track, which is completely subjective, and different for every voice, room, mix, microphone etc.
I have worked with multiple USB mics and they all come with the same problems.. I wasnt trying to "get people to click my link" I was just trying to offer some experience for people who work with stuff like I do on a budget. And these tips, no matter who you are, or what you say, work ALWAYS for me and the people Im affiliated with.. I mean listen to the quality I engineer, it speaks for itself, Im just trying to help the TRUE, HOME RECORDIING ARTISTS... god..
