The 'No Worries' bassline sound

[AnalogueDuke1]

Actually Casanova has given the best and the most accurate answer to your question.
If you had had listened to the music he linked you would have heard the samples butch took to create this track.

On a whole Casanova gave another valuable tip, namely that patience is important.

I appreciate the input but the bass sound is not taken from the originals.

its all about your kick bass relationship... there are tons of things on this forum with techniques to achieve this. if you want this specifically LISTEN to your mix as a whole and match it to a track like you've got. dunno but this is all stuff that comes with practice and you'll get it eventually and there is no one way to do it. that dennis ferrer interview stuff might also help you.
