This is a 12-bar solo/outro from one of the songs on Buddy Guy & Junior Wells' seminal album "Alone & Acoustic". Buddy plays this one acoustic solo. If you want to play it like Buddy, you have to grunt at the end of the second bar.

I transcribed this one a while ago and never put it up, but I decided that that was a waste, so here it is. If anyone wants me to write a little commentary on what's going on here, please send me a note.
