Hi Jill,
There isn't really any difference in the techniques and skills for playing an acoustic guitar versus an electric guitar. Guitar Fundamentals would be exactly the same course if Christopher had been using an acoustic guitar.
So you are in the right place.
Later, if you branch out into different styles, the techniques vary. Classic guitar has one style of fingerpicking, country guitar has another, modern acoustic/folk has a third. We teach all of those. But...the basic skills required before you start with each specific style are the same, and they are found in Guitar Fundamentals.
