I hope I don't insult anybody's knowledge here but if you know how to play dominant 7th scales, using two strings, and know where to play them you can manufacture an infinite amount of runs and licks. You should know how to play these scales on any two strings together vertically up and down the neck and horizontally across the neck.
A dom7 scale is just a major scale but played over the major chord a 5th higher. For example the C7 scale is just the F scale (but you start on the 5th degree of the F scale).
C7 on strings 6 & 5 = 3B+3A, 6+6, 8+8, 8B+8A, 11+11, 13+13, 13B+13A, 15B+15A
You can play the C7 scale when the song is changing from C to F (1 to 4). You can play the G7 scale when the song is changing from G back to root C (5 to 1).
If you're playing a blues then it's dom7 scales all the way.
Now for your homework go figure out how to play the C7 scale vertically on strings 5+3, 4+3, 6+4, 8+5.
