He seems like a humble dude and I'm sure he'll give me some tips at least but like I said, I don't think he's been active for nearly 2 months. :/
It's not like a special kick that's unique to him though, that's why I came here to see if anyone knew anything about mixing 808's with a sub-bass.
I've searched for tutorials but they're all too specific, they teach you how to make a particular sound and don't really explain how it works so I'm left not knowing how to fine tune it to my own needs.

I've tried hitting the books too but I still cant figure it out.

I appreciate the advice though pal.
I think I'll just keep experimenting while I wait for him to reply.
Meanwhile, if anyone knows the secret to fat, bassy 808 kicks then hmu ^^
