Well, it's a 12 bar blues, with the structure:


So you can just improvise everything around this structure, because Bonamassa also improvises everything there.

Edit: Some chords on 7, 8 and 10 bars weren't exactly correct, I've corrected them. Also, play the diminished chords without the 7th interval.
