NO. If you take the minor pentatonic scale and ADD the flat 5th notes, then you have the minor pentatonic blues scale. The "blues scale" is actually the minor pentatonic blues scale.
I have a link to a site that shows you a fretboard and you click on whatever scale you want and all of the notes pop-up on the fretboard. You can further delineate it by showing the note names (A, B, C, ETC) or by the note position (root, iii, v, etc). Here ya go....just possibly the BEST link you'll ever get:
