Disadvantage

Yet another 12 bar blues here... in E. The only difference is that in bars 9 and 10 there's half a bar of B followed by half a bar of A.So, it's like this:
EEEE EEEE EEEE EEEE
AAAA AAAA EEEE EEEE
BBAA BBAA EEEE EEEE

In the intro there's some play around the 2nd fret G string and open G string. Then some other E minor pentatonic stuff...
