I think he learned all that he knows and how to make growls because of the "how to make growl bass thread". He took that info got posted, started BA and thats why they have all the massive and huge growls. I think HookJr was really smart, cause the reason he started it was not only to help, and make a thread about it, but also to learn shit and make good music (no hate).
I've read almost the whole thread now, and from what I've seen, this is what you need to know and/or buy.
Basic VSTs/Plugins;
Massive
FM8
Sytrus
Harmor
Sylenth1
Razor (not really, but...)
WOW filter
Ohmnicide
Sausage Fattener
*insert compressor*
Any EQ <--- Important
And of course reverb and all the built-in stuff that every DAW has (if not, it's shit and you need to switch)
How to make them (the basics).
So the best way of making good growls is the most complicated.
The idea is to have a main VST (Massive, FM8, Harmor etc). You can either make just a single bass with no movement, or make a growl thats already pretty strong inside the box, you choose. Then you need to process it by (example);
Distort it (Ohmicide), Fatten it (SF), add a little WOW filter (only a little, to much will be obvious and thats now what we want), and then make an EQ automation. Then modulate the WOW filter, Eq and add some other things (that you want to add) and you should have a basic growl.
Back to our little chittchatt... You may ask yourself, why did you make this facking thread you facking bitch, there is already the "How to make a growl bass" thread, this thread has no facking point.
If you do that, Calm the fuck down, okay?

I made this thread so that we can sum up everything that has been said in "how to growl bases" thread, and just bring it to one place, cause we don't need all the stuff that doesn't help us.
Any more thoughts? Can we actually be smart, put our brains together and just make fucking growls.

Happy birthday, cheers.
