Only one scale.... Minor Pentatonic Scale.  What you are thinking of is the five positions the scale is found in and the key in which they reside....

The blues scale is very close to the Minor Pentatonic, but it has a b5 (#4) added. This will be covered in my next guitar course. :)

Technically, if there is a minor pentatonic scale (with or without any 'blue note') there must be a relative major pentatonic.
But AFAIK, the 'blues scale' is minor pentatonic with b5, as explained by Robert

Technically, if there is a minor pentatonic scale (with or without any 'blue note') there must be a relative major pentatonic.

Must be a relative major? Why, or where can I apply that info? What is the major relative of the six note blues scale (I think b5 of E is m3 of G, for example)? Basically, as far as I understand scales is that any scales can be seen as modes, meaning that a five note minor pentatonic has five modes, depending which note you start from... one of which is the major pentatonic. Not all scales are major or minor, but any scale that has 5 notes is a pentatonic.

I too think the original poster must have seen the minor pentatonic scale patterns that cover the whole fretboard. The scale itself is just the 5 notes, the patterns are just a practical tool for "seeing" and playing the five notes. The minor pentatonic in E is the open, 3, 5, 7th and tenth frets of the E string. What commonly is called the blues scale would then add the note at the 6th fret to that.

As far as scales played in blues, of course there can be seen to be many. It depends on the style of blues, some are jazzy or sweet, some sorrowful or blues rock. Minor pentatonic and six note blues scale are the common basis. But major pentatonic  (or mixolydian) and dorian modes are very common as well, for example, those just have some more notes in them. So, for example, dorian is like and extension of minor pentonic, like blues scale is.

You don't necessarily need to know the scale or it's name to be actually playing it. You can be playing the minor pentatonic all along, but using some extra notes in passing (bending or sliding, for example) if you so feel. Also, in my view of things,  if the backing track chords change, in essence you scale will change as well if you keep playing the same notes. You play the same notes, but they sound different if the chords (harmony) behind it is different. I think you should practice with your head (thinking) and play with your heart (expressing emotion). Meaning when you actually play, I think the point is to forget scales, instead think about scales when you transcirbing or something.

the Major Pentatonic scale is derived from the circle of 5ths
then we use the Its direct minor relative so we have Minor Pentatonic
the reason we use this is the Dominant 7th chords we have in progression
our 2 most powerful resolution notes are 3rd and 7th, in the Minor Pentatonic those are 3rd and b7th a tritone. So our 2 strongest points of resolution in key are now a tritone.
our weakest points of resolution are 1 and 5, but they do not match our strong points as being a tritone so we can add a b5th and get this
I would not suggest using a B5 as a landing note instead use it as a passing tone, however it now gives you 2 tritones in the scale and tritones are one of the strongest parts of the sound of the blues. The Blues is called the Devils music because of the DIABLO IN MUSICA or tritone and the Blues Scale has 2.
The guys who created the blues in no way were theorist, but they had a great sense of harmony and used that to create a Genre that has extreme influence on modern music.
They took one of the oldest scales in the world, the pentatonic (tone, dominant, dominant, dominant, dominant.) added a second tritone and ran with it. It may be a fluke it worked, but imagine music today without it's influence.

Don't get to involved in theory.  Those old bluesman of the day had no idea.  They just knew what sounded "right".  Find some lessons on youtube and take advantage of Roberts free lessons as well as some of his premimum advanced lessons.  Don't forget about Stevie snacks either at steviesnacks.com.
