If you're looking to spice up your acoustic playing in a rock way, I'd recommend if you're ready to start fitting in blues solos and modes while carrying on the rhythms. It's harder but it can be done. It's amazing how sometimes tones and the way you play chords and licks can make an acoustic sound more electric unplugged. In other words, you can still kick a lot of ass and play a mean guitar.
Acoustic Rock! Do it. If you want more examples.. check out John Mayer's version of Little Wing. This is what I mean about incorporating chords and solos together. You can do this on an acoustic. I do. Hope this helps.
