I've tabbed out 2 of the 3 choruses of Ryan's improvisation at the end of this video.
It's pretty awesome, and would be a great solo to learn if you're looking to up your single string chops.
I'd like to do a video going into a bit of the theory behind what he's doing, so if you have any questions, please let me know in the comment section below!
A lot of what he's doing involves pentatonic scales combined with bluesy chromaticism. He makes it sound really good :).
