I don't know what scale to use

Can someone point me in the direction of a blues scale that would be good to use with this chord progression. I'm just starting out, and I guess it would be like A pent blues or something like that since the progression is basically A(I), D(IV), A(I), E(V),A(I),D(IV), I, V, I. But here's what it looks like:
A 1 & 2 & 3 & 4 & D
e--------------------------|--------------------------|
B--------------------------|--2--2--2--2--2--2--2--2--|
G--2--2--2--2--2--2--2--2--|--2--2--4--4--2--2--2--2--|
D--2--2--4--4--2--2--2--2--|--0--0--0--0--0--0--3--3--|
A--0--0--0--0--0--0--3--3--|--------------------------|
E--------------------------|--------------------------|
E
e--------------------------|
B--------------------------|
G--------------------------|
D--2--2--2--2--2--2--2--2--|
A--2--2--4--4--2--2--2--2--|
E--0--0--0--0--0--0--3--3--|

Thanks for any help,

This is an A blues scale, 2 octaves. Its just like a minor pentatonic scale, but has an added b5th, which some people call the blue note.
Anyway, here it is;

---------------------------5---
-----------------------5-8-----
-----------------5-7-8---------
-------------5-7---------------
-------5-6-7-------------------
---5-8-------------------------

This may be the scale you already mentioned you knew, but in either case, you can use it to improvise over any blues chord progression in A. (Thats what your chord progression is, so...tada!)
Anywhooo, just get into it and play the chord tones in the scale over the chords in the progression, and you'll be set.

If I was to solo on that progression , I'd use A scale for the first line , and E scale for the second.
