So hey all. I'm trying to pick up my palm muting pace and I can't seem to get the hand of those little bursts of super fast palm muted picking that intersperse a lot of modern metal. You get that 'chugchugchugbrrrrrchugchugbrrrrrrr' sound going on. How are people achieving that? I try to keep the control and the speed goes and I get loads of tension in my wrist and arm and shoulder and fingers holding the pick. If I go for speed it's sloppy as hell and very rare that I manage to maintain consistent steady rhythm even for short burst. Driving me effing nuts! Quite happy to concede it's just practice but practice what and how!, and also that my old 44 year old joints and muscles just ain't going to comply but I'd like to at least give it a shot. Sorry if this seems a ridiculous question there is a degree to which I should have learned this years ago before I ever got near extended range guitars... but I didn't and now I'm absolutely completely in love with my 8 strings (I now have two agile Sceptres and I can't put them down). Any and all advice greatly appreciated and willingly received.
