THE MINOR BLUES SCALE ADD 3 ADD 7 contains the intervals: 1,b3,3,4,b5,5,b7,7.
These patterns are based on the standard MINOR BLUES SCALE boxes and add the 3 and 7 in the same formula.
All mapped out here for LEFT HANDED GUITAR including two simplified version because it contains stretches that some people might find awkward. The extra versions have fewer notes to give easier access to the sound.
