Your videos/audio tracks and tab are great learning tools, and a fine value for the price. I've purchased some of your products, and appreciate the free downloads, too.
The caliber of the musicians and material is excellent, and I think some of the hot country players would be a welcomed addition. The amazing country swing players of the past (Bob Will's band, Hank Garland, Jimmy Bryant, etc.), to the hot shot country pickers (Brent Mason and many, many others) and progressive bluesgrass musicians (David Grisman Qunintet and beyond) have a ton of musical concepts as well as scary chops to offer any guitarist. Exploring music genres other than blues, funk, jazz and hard rock is a good way to bring in more ideas and inspirations, and avoid sounding like everyone else. You already have Jerry Donahue and John Jorgenson guest appearance audio clips, so maybe they would be interested. For those who need something heavier, Guthrie Govan's dazzling Rhode Island Shred is a heavy does of twang that will challenge any guitarist.
Any products that explore bit of theory and technique (instead of just learning solos) would be of interest to me, too. BTW, Guthrie Govan's two books (Creative Guitar volumes 1 + 2) are highly recommended.
Keep up the great work!
