Hi Rob, and welcome on Talkbass!
I suggest that you first fill out your profile as much as you can:
http://www.talkbass.com/forum/profil...do=editprofile
That way, we can know what gear you use, what music you play, etc. This is a great help when someone asks for advice!
That said, please first check the Newbie links sticky at the top of each forum. (when there's one)
This is the link to the Technique's one:
Newbie Links: TECHNIQUE
(there are links about Walking bass lines)
Hope this helps!
Regards,
François
