Goals of the course:
1) more fluidity around the fretboard
2) sound more in time
3) increase finger strength, dexterity and mobility
4) play louder and faster
I ain't suggesting you can't use an acoustic or advocating for an electric.
Choose what ever guitar you want that will allow you to get what you want from this course.
Sprinters also do weight training.
I've only pointed out a couple of "limitations" you may discover with acoustic: slurs and speed.
