I have BGU and it's teaching me a lot. I love Griff's teaching style, and I'm currently working on lesson 11, Minor Blues. But eventually I plan to move more toward classic country sounds. SWS is on sale now but I don't know if it is the way for me to go once I finish BGU. Can anyone tell me if SWS will help, or if there is some other course I should consider to learn that twang?
