Can the string tension be altered on a guitar? Whenever I want to chug, literally in drop D with a metronome to practice my picking, the sting moves A LOT. No matter what angle I catch the string it seems to move massively with my pick, regardless of pick angle or how much of the pick is shown to the string. Even when fretting, the string will sometimes move over the top of the fret board if I catch it at the wrong angle. I see guys chugging alternate picking at an slight angle and it sounds so clean. All I can manage is a scraping sound where the string moves with my pick. Is it hardware issue or a technique issue?
