Question about tab

11/01/16 01:11:17PM

In general when reading Tab, I believe that you are to play all three (or four) strings.  However what are you supposed to do when the middle string (or I guess it could be the bass string) has an 0 or a 1 on it and no other strings have a notation?  Are you just supposed to play that string?  I'm referring to things like the second and eighth bar.  Thanks for any help.
