I've started the Blues 1 section now and still, everything is the same. The fundamentals of the guitar are the same whether your using an electric, a steel acoustic or a classical with nylon strings. As near as I can tell, other than when you eventually get to the effects sections and some specific lessons in other styles it won't matter if you've got an acoustic. I haven't found it to be an issue with my learning at all.
