Question:

"KevinT says, "HI, I checked out Brads scales lesson and have a question. I always warm up with minor pentatonic 1st position so I know it blindfolded, I am working on the others. My question is that when I just start messing around with improv it always ends up still sounding like scales. How do I get away from that? Thanks""
