Dude this bass line is hitten my woofers so hard!!! Im glad i stumbled across your page bro! I found through a comment you left on my tupac remake! Thats why giving good vibes where good vibes are due is a great idea!
No VST's, just samples mainly. Acid Pro to make the beat. Sound Forge to make the synth noise myself, and then edit to sound some kind of way. Had some keyboard samples I manipulated too. :D
