Basically the Blues Soloing Kickstart is a free 3 part video series that is about an hour in length, total, and focuses on teaching you how to get started with soloing the blues.

Some of the things you'll learn (for free...) include:
- A 4-note solo you can use anywhere
- A great practice technique for scales that isn't boring
- A 24 bar blues solo you can use in most 12 bar blues progressions (tab included)
- Hendrix and SRV style grace notes, for spicing up your solos
I've reviewed some of Griff's other courses, and the feedback I've heard from other people who have gone through them is positive, so all in all he's got a pretty good reputation on the interwebz.
Learning to play guitar, like most other areas of life, requires you to develop your own strong perspective on certain things, and the best way to do that is to get exposed to differing viewpoints. That's the main reason I recommend other guitar teachers such as Griff, to help give you alternative viewpoints to my own.
Besides - we're talking about an hour of free blues soloing lessons, so what's not to like?
