K, first, of all, thanks for the input :) So, to be clear, you're saying that when i do power chords i strum too wide and i should correct that ? What about "single notes" ? like in the solos ? And if so, how can i correct that ? On a different argument, i can do palm mute on power chords like on dookie or something punky, but only with down strokes, when i try to alternate picking palm mute power chord the sound is weird, could it be that my hand movement is the reason ?
