hold your pick at an angle if you already dont. it gives the least resistance against the string compared to picking it with the pick parallel. you'll hear less of a noise if you pick with an angle. something i noticed too. if i recall, in older recordings of rock bands, i think maybe on this hendrix cd i have, i remember faintly hearing the plucking noise, so i'd just say its technology being used at its best to reduce that noise, i.e. protools :P
