use a less flimsy pick. at the risk of breaking strings, this is a thought..the pick sound you hear is the bend of the pick releasing from one string and smacking the next string. the thicker the pick, the less smacking i hear. try the .75 mm and 1 mm picks and see how that works. what you could also be hearing is the pick smacking the edge of the sound hole and the pick guard. god knows i had to work on not doing that
