I just looked at these forums. And decided to join so I could post to this topic.
I wanted to add Buck Owens.
And his buckaroos. Don Rich was a helluva guitarist.
Also Jimmy Bryant & Speedy West have some crazy instrumentals. Jimmy Bryant is probably the fastest guitarist I've ever heard.
Spade Cooley.
Um. Merle Travis. Chet Atkins.
And of course Hank Sr., Johnny Cash, Willie Nelson.
