I am in the 12 bar blues section and only have an acoustic guitar. My question pertains to this lesson, but also some of the future ones coming up. I like alot of acoustic "stuff" but probably favor more blues and rock type music. When I am done with GF 2 I will probably go to the Rock section, and maybe blues. Can you play the 12 bar blues on acoustic and have it still be "right" (same for the rock and blues lessons coming up?)? My guess is "yes" perhaps with some limitations, but don't want to get myself down a wrong path. Maybe I just need to go buy an electric....
