Hey guys, what's the big deal about power chords?. I've been self-teaching myself (weird) about rock basics for about two years now in a electric guitar. I can't say I rock as hard as I wish to, but I'm not so bad at it. Have you ever tried the pentatonic-scale based chords on the third-eight? That's hard stuff, really. Power chords are piece of cake!.
A small hint form you guys afraid of the acoustic: Even though it's harder to learn, it provides more strength and speed when you practice on it, so it's worth the pain. electric guitar gets waaaayyyyy too easier after, so you'll become even better players when you switch to it.
Keep on the good work
