I'm looking for a bit of help with power chords. I'm working through fundamentals 2 and seem to have been on the power chord section for a lifetime. I just can't seem to get them sounding good. I have tried muting the open strings to stop them sounding, only hiting the three strings in the chord, which does improve things enormously but is quite hit and miss when I build speed up and even then to my ear they just don't sound like the ones Lisa plays. Any help or advice would be much appreciated. Eric
