I have been playing for about 5 months now and am just now very comfortable with fundamentals 2. I also play acoustic but I did break down and get a hollow body guitar. There are 2 main differences I see between acoustic and electric. First one is the action on the electric is much lower. The other is with just a little bit of effects mistakes are easily covered up in other words the acoustic is a little less forgiving "in my opinion".

However I love the sound of an acoustic guitar. I like just being able to pick it up and play without fiddling with this or that. So to answer your question it took me about 5 months to feel like yeah now I am getting somewhere hahaha. I am probably much slower than most folks as I practice everyday sometimes for a few hours (this includes reading not just playing). Now that I can switch chords easily I am trying different strumming patterens. Also still working on learning scales and positions and how chords are formed.

When I started I didn't know anything and just about everything I learned was here at GT. The best advice that I can give is go slow and make sure you can not only play the lessons in the fundamental courses but also that you understand them. I breezed through the first time then I did it again and really took my time. There is a lot to absorb there in addition to being able to just play the stuff.

If you really want to learn to play its not hard even when it is haha. I am only now "sometimes" getting frustrated with something hard. Aside from that F chord I really have been having too much fun to become frustrated. Don't hesitate to ask as many questions as you want. Most of all have fun with it,
