Watch the Change up online guitar lesson by Jeff Scheetz from 50 Blues Rock Rhythms You MUST Know

Here is a pretty simple blues based shuffle riff that starts out pretty clean, and actually works great muted with your right hand slightly touching the strings. Then, for the second section we do the same basic riff, however we use the full percussive strum to get the most sound. This way of playing the same part, only a little mellower at first and then making it a bit heavier is a standard writing technique with grunge tunes, so here we just use it in a blues setting.
